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

Answer:

7/12lb

Step-by-step explanation:

5-1 2/3-2 3/4

=5-5/3-11/4

=10/3-11/4

=40/12-33/12

=7/12lb

Answer 2

Answer:

$\frac{7}{12}$

Step-by-step explanation:

There was an initial amount of 5 lbs.

$1\frac{2}{3}+2\frac{3}{4}=4\frac{5}{12}$

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

$5 - 4\frac{5}{12}=\boxed{\frac{7}{12}}$

(7/12) of sugar should be remaining.

Hope this helps.
