Question

1Let's find-12.First, write the addition so the fractions have denominator 12.Then add.=1+-12- +4=1212Х5?

Answer 1

Given:

$\frac{1}{4}+\frac{1}{12}$

Making the denominator 12.

$\text{ We know that 4}\times3=12.$

$\frac{1}{4}+\frac{1}{12}=\frac{1\times3}{4\times3}+\frac{1}{12}$

$\frac{1}{4}+\frac{1}{12}=\frac{3}{12}+\frac{1}{12}$

Add the numerator.

$\frac{1}{4}+\frac{1}{12}=\frac{3+1}{12}$

$\frac{1}{4}+\frac{1}{12}=\frac{4}{12}$

Simplify.

$\frac{1}{4}+\frac{1}{12}=\frac{1}{3}$

Hence the answer is

$\frac{1}{4}+\frac{1}{12}=\frac{3}{12}+\frac{1}{12}=\frac{1}{3}$
