Step-by-step solutions included
Exercise #1

Write the fraction shown in the picture, in words:

Step-by-Step Solution

To solve this problem, we need to convert the visual representation of a fraction into words. Let's break down the process step by step:

Step 1: Identify the given visual information

The given image is a circle, which represents a whole. It has two distinct halves divided by a vertical line. One half is shaded, which indicates the fraction that we need to express in words.

Step 2: Determine the fraction represented

Given that one half of the circle is shaded, it indicates that this is one part of two equal parts.

Step 3: Write the fraction in words

The fraction that corresponds to one out of two equal parts is 12 \frac{1}{2} , expressed in words as "half."

Therefore, the fraction shown in the picture, expressed in words, is Half.

Answer:

Half

Exercise #2

Write the fraction shown in the picture, in words:

Step-by-Step Solution

To solve this problem, we need to translate the visual fraction representation into words:

  • Step 1: Recognize the grid is a 3x3 matrix, making a total of 3×3=9 3 \times 3 = 9 squares.
  • Step 2: Count the shaded squares, which appear to number 3 squares.
  • Step 3: Write this as a fraction: the number of shaded squares (3) over the total squares (9). This fraction is 39\frac{3}{9}.
  • Step 4: Convert the fraction 39\frac{3}{9} into words. This is read as "three ninths".

Thus, the fraction shown in the picture, in words, is three ninths.

Answer:

Three ninths

Exercise #3

Write the fraction shown in the picture, in words:

Step-by-Step Solution

To solve the problem of expressing the fraction in words, follow these steps:

  • Step 1: Count the total number of sections in the grid to determine the denominator.
  • Step 2: Count the number of shaded sections to determine the numerator.
  • Step 3: Write the fraction as a phrase using words.

Now, let's work through these steps:

Step 1: The grid consists of a 3×33 \times 3 layout, which means there are 9 total sections. Therefore, the denominator of our fraction is 9.

Step 2: Observe and count the number of shaded sections within the grid. In this case, there are 4 shaded sections. Therefore, the numerator is 4.

Step 3: With a fraction identified as 49\frac{4}{9}, we can express this in words as "four ninths."

Therefore, the solution to the problem is four ninths.

Answer:

Four ninths

Exercise #4

Write the fraction shown in the picture, in words:

Step-by-Step Solution

Step 1: Count the total sections
The circle is divided into 8 equal sections.
Step 2: Count the shaded sections
There are 6 shaded sections in the diagram.
Step 3: Formulate the fraction
The fraction of the shaded area is 68\frac{6}{8}.
Step 4: Express in words
The fraction 68\frac{6}{8} in words is "six eighths".

Therefore, the solution to the problem is "six eighths".

Answer:

Six eighths

Exercise #5

Write the fraction shown in the drawing, in numbers:

Step-by-Step Solution

The number of parts in the circle represents the denominator of the fraction, and the number of colored parts represents the numerator.

The circle is divided into 4 parts, 3 parts are colored.

34 \frac{3}{4}

Answer:

34 \frac{3}{4}

Frequently Asked Questions

What is a denominator in a fraction?

+
The denominator is the bottom number in a fraction that shows how many equal parts make up the whole. For example, in 3/8, the denominator 8 means the whole is divided into 8 equal parts.

How do you find the denominator of a fraction?

+
To find the denominator, look at the bottom number below the fraction bar. In any fraction like 5/7, the denominator is always the number at the bottom (7 in this case).

What does the denominator tell you about fractions?

+
The denominator tells you: 1) How many equal parts the whole is divided into, 2) The size of each part (smaller denominators = larger parts), 3) What type of fraction you're working with (halves, thirds, quarters, etc.).

Can denominators be zero or negative numbers?

+
Denominators cannot be zero because division by zero is undefined in mathematics. Denominators can technically be negative, but in elementary fractions, we typically use positive denominators to represent parts of a whole.

What's the difference between numerator and denominator?

+
The numerator (top number) shows how many parts you have, while the denominator (bottom number) shows how many total parts make up the whole. Think of it as 'parts you have' over 'total parts available'.

How do you write fractions with the same denominator?

+
To write fractions with the same denominator, keep the bottom number the same and change only the numerator. For example, fractions with denominator 4: 1/4, 2/4, 3/4, 5/4, etc.

Why is understanding denominators important for kids?

+
Understanding denominators helps students: visualize parts of a whole, compare fraction sizes, add and subtract fractions, solve real-world problems involving sharing and measurement, and build foundation skills for advanced math.

What are common mistakes students make with denominators?

+
Common mistakes include: confusing numerator and denominator positions, thinking larger denominators mean larger fractions, forgetting that denominators represent the whole, and not understanding that denominators show equal parts, not just any parts.
