Question

I bought a 5lb bag of sugar. I used 1 2/3 for cookies and 2 3/4 for cake. How much sugar do I have left?

Answer 1

`(7)/(12)`

Explanation:

There was an initial amount of 5 lbs.

`1(2)/(3)+2(3)/(4)=4(5)/(12)`

4 (5/12) of the sugar was used.

`5 - 4(5)/(12)=\boxed{(7)/(12)}`

(7/12) of sugar should be remaining.

Hope this helps.

5-1 2/3-2 3/4

=5-5/3-11/4
