Understanding How do you simplify fractions?

Complete explanation with examples
How do you simplify fractions? Or, how do you reduce fractions?

In most cases, when fractions are introduced to students as a new topic in the classroom, the initial reaction is: "Here's another complex subject we have to deal with." But then, reactions change and fractions are seen as a kind of enjoyable game that is more of a technical challenge. So, what's particularly important about fractions? Understanding their meaning, the division of roles between the numerator and the denominator, and how to reduce them. Is it difficult to reduce fractions? Not really.

So, when will you need to reduce the given fractions?

  • At the time it's required in an exercise/test.
  • In case you want to work with smaller fractions.

Examples with solutions for How do you simplify fractions?

Step-by-step solutions included
Exercise #1

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 #2

Increase the following fraction by a factor of 2:

1012= \frac{10}{12}=

Step-by-Step Solution

To solve this problem, we need to increase the fraction 1012 \frac{10}{12} by a factor of 2. This can be accomplished by multiplying both the numerator and the denominator by 2, to maintain the value relationship while doubling the fraction.

Let's go through the solution step-by-step:

  • Step 1: Identify the original fraction, which is 1012 \frac{10}{12} .
  • Step 2: Multiply the numerator by 2. This results in 10Γ—2=20 10 \times 2 = 20 .
  • Step 3: Multiply the denominator by 2. This results in 12Γ—2=24 12 \times 2 = 24 .
  • Step 4: Construct the new fraction 2024 \frac{20}{24} .

The fraction 2024 \frac{20}{24} is the result of increasing the original fraction by a factor of 2. In this case, this number is confirmed to be the correct answer.

Therefore, the solution to the problem is 2024 \frac{20}{24} .

Answer:

2024 \frac{20}{24}

Exercise #3

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}

Exercise #4

Increase the following fraction by a factor of 5:

310= \frac{3}{10}=

Step-by-Step Solution

To solve the problem of increasing the fraction 310 \frac{3}{10} by a factor of 5, follow these steps:

  • Step 1: Multiply the numerator by 5.
    The original numerator is 3, so 3Γ—5=15 3 \times 5 = 15 .
  • Step 2: Multiply the denominator by 5.
    The original denominator is 10, so 10Γ—5=50 10 \times 5 = 50 .
  • Step 3: Write the new fraction.
    The resulting fraction after applying the factor is 1550 \frac{15}{50} .

Thus, when we increase the fraction 310 \frac{3}{10} by a factor of 5, we get 1550 \frac{15}{50} .

Therefore, the correct answer is 1550 \frac{15}{50} .

Answer:

1550 \frac{15}{50}

Frequently Asked Questions

How do you reduce fractions to lowest terms?

+
To reduce fractions to lowest terms, divide both the numerator and denominator by their greatest common factor (GCF). For example, 4/10 reduces to 2/5 by dividing both by 2. Keep dividing until no common factors remain except 1.

What is the easiest way to simplify fractions?

+
The easiest way is to find the largest number that divides evenly into both the numerator and denominator, then divide both by that number. Start by checking if both numbers are even (divisible by 2), then try 3, 5, and other common factors.

Can all fractions be reduced?

+
No, not all fractions can be reduced. Fractions like 3/7 or 5/8 are already in lowest terms because their numerator and denominator share no common factors other than 1. These are called irreducible or simplified fractions.

What are the steps to reduce fractions?

+
Follow these steps: 1) Find the greatest common factor (GCF) of the numerator and denominator, 2) Divide both the numerator and denominator by the GCF, 3) Check if the result can be reduced further, 4) Repeat until no common factors remain.

How do you expand fractions?

+
To expand fractions, multiply both the numerator and denominator by the same number. For example, 1/3 can be expanded to 2/6 by multiplying both by 2, or to 5/15 by multiplying both by 5. This creates equivalent fractions.

Why is it important to reduce fractions?

+
Reducing fractions makes them easier to work with in calculations, compare with other fractions, and understand visually. Simplified fractions like 1/2 are clearer than equivalent complex fractions like 50/100.

What's the difference between reducing and expanding fractions?

+
Reducing fractions makes them simpler by dividing the numerator and denominator by a common factor. Expanding fractions makes them more complex by multiplying both parts by the same number. Both create equivalent fractions.

How do you know when a fraction is fully reduced?

+
A fraction is fully reduced when the numerator and denominator have no common factors other than 1. You can check by finding the GCF - if it equals 1, the fraction cannot be reduced further.
