Question

Chad bought a box of raisins. he gave 1/6 of it to one brother, 1/4 to another brother, and he kept the rest for himself. what fraction did he keep?

Answer 1

Greetings!

This can be solved by creating a simple equation.

`1/4+1/6+x=1`

Solve for x.

`1/4+1/6+x=1`
Find the LCM.

`3/12+2/12+x=1`

`5/12+x=1`
Add -5/12 to both sides.

`(5/12+x)+(-5/12)=(1)+(-5/12)`
Simplify.

`x=1/1-5/12`
Find the LCM.

`x=12/12-5/12`

`x=7/12`

He kept 7/12 of the raisins for himself.

Hope this helps.
