What is 5x3

5 answers

Lois got 27 problems right on a math test. if this is 90% of the test, how many problems were on the test?
5 + 5 + 5 = 15
or
3 + 3 + 3 + 3 + 3 = 15
27 = 0.90 N

N = 27/ 0.90 = 30
5x3= 15
(tally marks) ||||| ||||| ||||| Three groups of five:)
What kind of question is this lol XP
It’s 15 but you already got the answer so it doesn’t matter
