How To Master Multiplying and Dividing Fractions – A Step-by-Step Guide

Multiplying and dividing fractions are important arithmetic operations used to resolve numerous mathematical issues. Understanding these operations is essential for college kids and people trying to improve their mathematical expertise.

To multiply fractions, we multiply the numerators (high numbers) and the denominators (backside numbers) of the fractions. For instance, to multiply 1/2 by 3/4, we multiply 1 by 3 and a pair of by 4, which supplies us 3/8.
To divide fractions, we invert (flip) the second fraction and multiply it by the primary fraction. For instance, to divide 1/2 by 3/4, we invert 3/4 to 4/3 and multiply it by 1/2, which supplies us 2/3.
