Question

3 1/4 x 2/3 = ??grade. 7th

Answer 1

Given the expression:

$3\cdot\frac{1}{4}\cdot\frac{2}{3}$

Fist step is to express the "whole" as a fraction, for this, divide it by 1

$\frac{3}{1}\cdot\frac{1}{4}\cdot\frac{2}{3}$

Second step, multiply the first two fractions:

$\frac{3}{1}\cdot\frac{1}{4}=\frac{3\cdot1}{1\cdot4}=\frac{3}{4}$

Third step, multiply the result of the first operation by the third fraction:

$\frac{3}{4}\cdot\frac{2}{3}=\frac{3\cdot2}{4\cdot3}=\frac{6}{12}$

Finally simplify the expression, both the numerator and denominator are divisible by 6 so:

$\frac{6\div6}{12\div6}=\frac{1}{2}$

Then the result for the given expression is 1/2

$3\cdot\frac{1}{4}\cdot\frac{2}{3}=\frac{1}{2}$
