Question

Mona bought 3 3/8 pounds of cheese. She used 2 3/4 pounds to make sandwiches. Write and solve an equation to find how much cheese is left.

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

cheese:

purchased amount = 3 3/8 lb

used amount = 2 3/4

Step 02:

equation:

remaining amount = purchased amount - used amount

`\begin{gathered} \text{remaining amount = 3 3/8 - 2 3/4 }=\text{ (3 + }(3)/(8))\text{ - (2 + }(3)/(4)) \\ \text{ } \end{gathered}`
`\text{remaining amount = }(27)/(8)\text{ - }(11)/(4)=(5)/(8)`

The answer is:

5/8 lb = 0.625 lb
