Answer:
14 tests
Explanation:
For this question, we want to find the unit rate.
To do this, we must divide 10 by 5
10/5 = 2
So, that means that he takes 2 tests per week.
If he takes 2 tests per week, How many will he take in 7 weeks?
since 2 tests = 1 week, we can find out 7 weeks by multiplying each side by 7.
2*7 = 1 *7
2 * 7 = 14
1 * 7 = 7
14 tests = 7 weeks
So, in 7 weeks, he will take 14 tests.
