You can follow these steps to multiply a fraction by a whole number:
- Write the whole number as a fraction with a denominator of 1.
- Multiply the numerators.
- Multiply the denominators.
- Simplify. , if needed. If your answer is greater than 1, you may want to write your answer as a mixed number.
What is the rule of fractions?
To add or subtract fractions they must have the same denominator (the bottom value). If the denominators are already the same then it is just a matter of either adding or subtracting the numerators (the top value). If the denominators are different then a common denominator needs to be found.
How to multiply all fractions into improper fractions?
1 The first step is to convert all the fractions into improper fraction. 2 Multiply the numerators and place the product at the top. 3 Multiply the denominators and place the product at the bottom. 4 Simplify the result if possible.
How to calculate the fraction of 3 1 / 8?
a) Multiply the whole number 2 by the denominator 8. Whole number 2 equally 2 * 8 b) Add the answer from previous step 16 to the numerator 3. New numerator is 16 + 3 = 19 c) Write previous answer (new numerator 19) over the denominator 8.
How to calculate fraction of whole number 2 equally?
Whole number 2 equally 2 * 7 b) Add the answer from previous step 14 to the numerator 1. New numerator is 14 + 1 = 15 c) Write a previous answer (new numerator 15) over the denominator 7. Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD (165, 21) = 3.
How to calculate the fraction in fraction calculator?
New numerator is 14 + 1 = 15 c) Write a previous answer (new numerator 15) over the denominator 7. Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD (165, 21) = 3. In the next intermediate step, , cancel by a common factor of 3 gives 55 7.
