Question

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

Answer 1

Given:

`(1)/(4)+(1)/(12)`

Making the denominator 12.

`\text{ We know that 4}*3=12.`

`(1)/(4)+(1)/(12)=(1*3)/(4*3)+(1)/(12)`

`(1)/(4)+(1)/(12)=(3)/(12)+(1)/(12)`

Add the numerator.

`(1)/(4)+(1)/(12)=(3+1)/(12)`

`(1)/(4)+(1)/(12)=(4)/(12)`

Simplify.

`(1)/(4)+(1)/(12)=(1)/(3)`

Hence the answer is

`(1)/(4)+(1)/(12)=(3)/(12)+(1)/(12)=(1)/(3)`
