Example Question #61 : Use The Four Operations With Whole Numbers To Solve Problems

Justin has \(\displaystyle 4\) shelves in his room. Each shelf holds \(\displaystyle 7\) toys. If Justin has \(\displaystyle 30\) toys, how many toys don't fit on the shelves? 

 

Possible Answers:

\(\displaystyle 1\)

\(\displaystyle 2\)

\(\displaystyle 0\)

\(\displaystyle 3\)

\(\displaystyle 4\)

Correct answer:

\(\displaystyle 2\)

Explanation:

To solve this problem, we first need to find out how many of Justin's toys will fit on the shelves. If we have \(\displaystyle 4\) shelves, and \(\displaystyle 7\) toys fit on each shelf, we can multiply those two numbers together to find out the total number of toys that will fit. Let's let \(\displaystyle f\) represent the number of toys that will fit. 

\(\displaystyle 4\times7=f\)

\(\displaystyle 28=f\)

Justin has \(\displaystyle 30\) toys, so to find out how many don't fit on the shelves we need to know what is left over, so we subtract. Let's let \(\displaystyle t\) represent the number of toys left over. 

\(\displaystyle 30-28=2\)

\(\displaystyle 2=t\)
