Calculators are reliable tools for solving simple mathematical problems and advanced calculations like trigonometry. Whether you’re cooking, tracking BMI, or planning a construction project, calculators will make your life easy. In this topic, we are going to talk about like fractions calculators.
A like fractions calculator is a tool used to perform operations on fractions that have the same denominator.
Since like fractions share the same denominator, this calculator helps simplify the process of addition, subtraction, multiplication, or division, making calculations much easier and faster, saving time and effort.
Given below is a step-by-step process on how to use the calculator:
Step 1: Enter the fractions: Input the fractions that you want to operate on into the given fields.
Step 2: Choose the operation: Select the operation (addition, subtraction, multiplication, division) you want to perform.
Step 3: Click on calculate: Click on the calculate button to perform the operation and get the result.
Step 4: View the result: The calculator will display the result instantly.
To operate on like fractions, follow these simple steps: Since the denominators are the same, you can perform the arithmetic operation directly on the numerators.
Addition: Add the numerators and keep the denominator the same.
Subtraction: Subtract one numerator from the other and keep the denominator.
Multiplication: Multiply the numerators together and the denominators together.
Division: Multiply by the reciprocal of the divisor fraction.
When using a like fractions calculator, there are a few tips and tricks you can use to make it easier and avoid mistakes: Always double-check the entered fractions to ensure they are correct.
Remember to simplify your answer, if possible, after performing the operation.
Use the calculator for quick verification of manual calculations, especially in exams.
Avoid common mistakes like confusing numerators with denominators.
We may think that when using a calculator, mistakes will not happen.
But it is possible for children to make mistakes when using a calculator.
Add these like fractions: 3/5 and 2/5.
Since the fractions have the same denominator, add the numerators: 3 + 2 = 5
So, 3/5 + 2/5 = 5/5 = 1.
Because the denominators are the same, you only need to add the numerators.
The result is a whole number because the fraction simplifies to 1.
Subtract the like fractions: 7/8 and 3/8.
Since the denominators are the same, subtract the numerators: 7 - 3 = 4
So, 7/8 - 3/8 = 4/8 = 1/2 after simplification.
The denominators are the same, so you subtract the numerators.
Simplifying 4/8 results in 1/2.
Multiply the like fractions: 2/9 and 4/9.
Multiply the numerators and the denominators: (2 × 4) / (9 × 9) = 8/81
So, 2/9 × 4/9 = 8/81.
Multiply the numerators together and the denominators together to get the result.
The fraction is already in its simplest form.
Divide the like fractions: 5/12 by 1/12.
Multiply by the reciprocal of the divisor fraction: (5/12) × (12/1) = 5
So, 5/12 ÷ 1/12 = 5.
Dividing by a fraction is equivalent to multiplying by its reciprocal.
The result is a whole number in this case.
Add these like fractions: 11/15 and 2/15.
Add the numerators since the denominators are the same: 11 + 2 = 13
So, 11/15 + 2/15 = 13/15.
Simply add the numerators while keeping the denominator the same.
The result is already simplified.
