Simplification and Expansiono f Simple Fractions

To amplify fractions

We will perform the same multiplication operation on the numerator and the denominator: the value of the fraction will be preserved.

You can expand as many times as you want and by any number.

To simplify fractions:

We will perform the same division operation on the numerator and the denominator: the value of the fraction will be preserved.

This can only be done with a number that is completely divisible by both the numerator and the denominator.

It is possible to simplify only until reaching a fraction in which it is not possible to find a number that divides without remainder both in the numerator and the denominator.

Exercise #2

Increase the following fraction by a factor of 10:

110= \frac{1}{10}=

Step-by-Step Solution

To solve this problem, we need to increase the fraction 110 \frac{1}{10} by a factor of 10. We will accomplish this by multiplying both the numerator and the denominator by 10.

  • Step 1: Multiply the numerator, 1, by the factor 10:
    1Γ—10=10 1 \times 10 = 10
  • Step 2: Multiply the denominator, 10, by the factor 10:
    10Γ—10=100 10 \times 10 = 100

The fraction 110 \frac{1}{10} , increased by a factor of 10, results in 10100 \frac{10}{100} .

After performing these steps, we have successfully increased the fraction by a factor of 10 to reach 10100 \frac{10}{100} .

The correct answer from the provided choices is: 10100 \frac{10}{100} .

Answer:

10100 \frac{10}{100}

Exercise #3

Increase the following fraction by a factor of 10:

116= \frac{1}{16}=

Step-by-Step Solution

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

  • Step 1: Multiply the numerator of 116 \frac{1}{16} , which is 1, by the factor of 10.
  • Step 2: Use the same denominator, which remains as 16.

Now, let's work through each step:
Step 1: The numerator is 1. Multiplying this by the factor 10 gives us 1Γ—10=10 1 \times 10 = 10 .
Step 2: The denominator remains 16, so the fraction becomes 1016 \frac{10}{16} .

After performing the multiplication, the fraction becomes 1016 \frac{10}{16} . To simplify this solution, we can reduce 1016 \frac{10}{16} by dividing both the numerator and the denominator by their greatest common divisor, which is 2. This results in the final reduced fraction 58 \frac{5}{8} . However, our task was to simply multiply and not reduce, so we end with:

The solution to the problem is 10160 \frac{10}{160} .

Answer:

10160 \frac{10}{160}

Exercise #4

Increase the following fraction by a factor of 2:

35= \frac{3}{5}=

Step-by-Step Solution

Let's multiply both the numerator and denominator by 2 as follows:

3Γ—25Γ—2=610 \frac{3\times2}{5\times2}=\frac{6}{10}

Answer:

610 \frac{6}{10}

Video Solution
Exercise #5

Increase the following fraction by a factor of 3:

610= \frac{6}{10}=

Step-by-Step Solution

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

  • Step 1: Identify the original fraction.
  • Step 2: Multiply the numerator by the factor provided, keeping the denominator the same.
  • Step 3: Compute the computation to give the expanded fraction.

Now, let's work through each step:
Step 1: The original fraction given is 610 \frac{6}{10} .
Step 2: Multiply the numerator 6 6 by the factor 3 3 , which yields 6Γ—3=18 6 \times 3 = 18 . The denominator remains 10 10 , forming the new fraction 1810 \frac{18}{10} .
Step 3: To express the fraction with a factor of 3 for both parts, multiply both numerator and denominator by the same 3 3 to illustrate the transformation properly: 1810Γ—3=1830 \frac{18}{10 \times 3} = \frac{18}{30} .

Therefore, the solution to the problem is 1830 \frac{18}{30} .

Answer:

1830 \frac{18}{30}

Frequently Asked Questions

What does it mean to expand or amplify a fraction?

+
Expanding a fraction means multiplying both the numerator and denominator by the same number. This creates an equivalent fraction that looks different but has the same value. For example, 1/2 expanded by 4 becomes 4/8.

How do you simplify a fraction step by step?

+
To simplify a fraction: 1) Find a number that divides both numerator and denominator evenly, 2) Divide both parts by that number, 3) Repeat until no common factors remain. For example, 24/16 Γ· 8 = 3/2.

When can a fraction not be simplified anymore?

+
A fraction cannot be simplified when there is no number (other than 1) that divides both the numerator and denominator without a remainder. For example, 3/5 cannot be simplified because 3 and 5 share no common factors.

Does expanding a fraction make it bigger?

+
No, expanding a fraction does not change its actual value or make it bigger. The fraction only looks different with larger numbers, but represents the same amount. For instance, 1/2 = 4/8 = 8/16 all represent the same value.

What are equivalent fractions in simple terms?

+
Equivalent fractions are different fractions that represent the same value. They are created by multiplying or dividing both the numerator and denominator by the same number. Examples include 2/4, 3/6, and 4/8, which all equal 1/2.

How do you find missing numbers in fraction problems?

+
To find missing numbers: 1) Compare the known parts of both fractions, 2) Determine what number was used to multiply or divide, 3) Apply the same operation to the unknown part. If 2/8 = 4/β–‘, then 2Γ—2=4, so 8Γ—2=16.

What is the difference between simplifying and expanding fractions?

+
Simplifying uses division to make fractions smaller and easier to work with, while expanding uses multiplication to create equivalent fractions with larger numbers. Both preserve the fraction's value but change its appearance.

Why is it important to learn fraction reduction and expansion?

+
These skills are essential for adding, subtracting, and comparing fractions. They help solve math problems more easily and are used in real-life situations like cooking, measurements, and calculating proportions in recipes or construction projects.
