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 f

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.
