Complete explanation with examples

Remainder

What is a remainder:

The remainder is the part left over when we divide a number by another number and it does not divide evenly.
In a fraction, we will see that the remaining part also needs to be divided equally, and this will be our remainder – exactly that equal part that is divided among everyone!

Remainder of a fraction

In an improper fraction where the numerator is greater than the denominator, there are 33 ways to find the remainder:

  1. The first method – Understanding approach
  2. The second method – Mathematical approach
  3. The third method – Converting an improper fraction to a mixed number

Remainder of a decimal fraction

To find the remainder of a decimal fraction, proceed as follows:
Everything that appears to the left of the decimal point is called the whole number.
Everything that appears to the right of the decimal point is called the remainder.

Remainder of a mixed number

In a mixed number composed of a whole number and a fraction -
the remainder is always the non-whole part!
This means that the remainder is always the fractional part of the mixed number.

Exercise #1

Determine the numerical value of the shaded area:

Step-by-Step Solution

To solve this problem, let's analyze the shaded area in terms of grid squares:

  • Step 1: The top rectangle in the grid is completely filled. Let's count the shaded squares horizontally: There are 10 squares across aligned vertically in 1 row, giving 11 as the shaded area.
  • Step 2: The bottom rectangle is partially filled. Observe it spans 66 squares horizontally by 11 square height in the grid row. The shaded area will, therefore, be 0.60.6 as it spans only 60%60\% of the horizontal extent.
  • Step 3: Add both shaded areas of the rectangles from step 1 and step 2: 11 (top) and 0.60.6 (bottom).

Thus, the total shaded area is 1+0.6=1.61 + 0.6 = 1.6.

Therefore, the solution to the problem is 1.61.6.

Answer:

1.6

Exercise #2

Determine the numerical value of the shaded area:

Step-by-Step Solution

To solve this problem, we'll follow a few simple steps to calculate the shaded area by counting strips and converting to a decimal:

  • Step 1: Identify the total number of vertical strips in the entire rectangle. From the diagram, there are 10 strips in total.
  • Step 2: Count the number of shaded vertical strips. According to the diagram, 5 strips are shaded.
  • Step 3: Write the fraction of the shaded area relative to the total area. The fraction is 510\frac{5}{10}.
  • Step 4: Simplify the fraction, which is already simplified, and then convert it to a decimal. 510=0.5\frac{5}{10} = 0.5.

Therefore, the solution to the problem is 0.5 0.5 .

Answer:

0.5

Exercise #3

Determine the numerical value of the shaded area:

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the total number of divisions in the grid.
  • Step 2: Count the number of shaded divisions.
  • Step 3: Calculate the fraction of the shaded area relative to the total.

Now, let's work through each step:
Step 1: The grid is divided into 10 equal vertical columns.
Step 2: Of these columns, 1 column is shaded.
Step 3: Since there are 10 columns in total, the shaded area represents 110\frac{1}{10} of the total area.

Finally, the fraction 110\frac{1}{10} can be expressed as the decimal 0.10.1.

Therefore, the numerical value of the shaded area is 0.10.1.

Answer:

0.1

Exercise #4

Determine the numerical value of the shaded area:

Step-by-Step Solution

To solve this problem, let's follow the outlined plan:

  • Step 1: Count the number of shaded sections.
  • Step 2: Count the total number of sections in the rectangle.
  • Step 3: Express the number of shaded sections as a fraction of the total sections.
  • Step 4: Convert this fraction to a decimal to find the numerical value.

Now, let's apply these steps:
Step 1: The given diagram shows that there are 4 vertical stripes shaded.
Step 2: The total number of vertical stripes (including both shaded and unshaded) is 10.
Step 3: The fraction of shaded area is 410\frac{4}{10}.
Step 4: Convert 410\frac{4}{10} to a decimal. This equals 0.40.4.

Therefore, the numerical value of the shaded area is 0.4.

Answer:

0.4

Exercise #5

What is the marked part?

Step-by-Step Solution

Let's begin:

Step 1: Upon examination, the diagram divides the rectangle into 7 vertical sections.

Step 2: The entire shaded region spans the full width, essentially covering all sections, so the shaded number is 7.

Step 3: The fraction of the total rectangle that is shaded is 77 \frac{7}{7} .

Step 4: Simplifying, 77 \frac{7}{7} becomes 1 1 .

Therefore, the solution is marked by the choice: Answers a + b.

Frequently Asked Questions

What is a remainder in math fractions?

+
A remainder is the part left over when dividing numbers that don't divide evenly. In fractions, it's the equal part that needs to be divided among everyone after the whole number portions are distributed.

How do you find the remainder of an improper fraction?

+
There are three methods: 1) Understanding approach - find how many times the denominator fits into the numerator, 2) Mathematical approach - find the largest multiple and subtract, 3) Convert to mixed number where the fractional part is the remainder.

What is the remainder in decimal fraction 75.08?

+
The remainder is 0.08. Everything to the right of the decimal point is the remainder, not just the last digit. Remember to include all decimal places when identifying the remainder.

How to find remainder in mixed numbers like 5 2/3?

+
In mixed numbers, the remainder is always the fractional part. For 5 2/3, the remainder is 2/3 because it represents the non-whole portion of the mixed number.

When does an improper fraction have no remainder?

+
An improper fraction has no remainder when the numerator is exactly divisible by the denominator. For example, 8/4 = 2 with no remainder because 4 fits into 8 exactly 2 times.

What are the steps to find remainder using mathematical approach?

+
Steps: 1) Find the largest number close to the numerator that's divisible by the denominator, 2) Divide to get the whole number, 3) Subtract (whole number Γ— denominator) from the original numerator, 4) Write the result over the original denominator.

How do you solve remainder word problems with fractions?

+
Divide the total amount by the number of parts, convert to a mixed number if needed, and identify the fractional part as the remainder. For example, if 20 shekels are split among 3 people: 20Γ·3 = 6 2/3, so each gets 6 shekels with 2/3 remainder.

What's the difference between remainder in fractions vs decimals?

+
In fractions, the remainder is the fractional part after division (like 2/3). In decimals, the remainder is everything after the decimal point (like 0.75). Both represent the leftover portion that couldn't form complete wholes.
