Question

There are 24 students in a science class. Mr. Sato will give each pair of students 3 magnets. So far, Mr. Sato has given 9 pairs of students their 3 magnets. How many more magnets does Mr. Sato need so that each par of students has exactly 3 magnets? Write an order of operations to solve it.

Answer 1

To tell how many pairs there are, divide 24 by 2; so 24/2= 12.
There’s 12 pairs.
He’s given out 9 pairs. 12-9= 3.
He needs to give out 3 more pairs.
3*3=9.
Mr. Sato needs to give out 9 more magnets.
