Question

I need help with math work because I struggle in math

Answer 1

Your wording is messed up...

I think you are saying: Amy ate 1/4 of a bag of chips and someone else

ate 2/3 of the remainder.

 

If we start with c chips:

 

c - (1/4)c - (2/3)((1/4)c) =

c - (1/4)c - (2/12)c =

c - (1/4)c - (1/6)c =

(12/12)c - (3/12)c - (2/12)c =

(12-3-2)/12)c =

(7/12)c left

 

We have 7/12 of the chips left in the bag which means 5/12 of the chips were eaten.
