Question

How to solve these types of ACT Math Questions? I need help understanding them ( I'm testing tomorrow)

Answer 1

are there answer choices?

Answer 2

for the first one just multiply 3 x 5 x 6 x 2 to get the total number of outfits

Answer 3

number 2 is easy too
it gives us the total length
so you have to add the ratios 2:5 for the total relationship
2+5=7
21/7=3
so just mutiply 3 by 2 since it is asking for the smaller part
so the small is 6 in and the larger part is 15 inches

Answer 4

when given a ratio, add the two parts, 2:5 to get the "total" 7

divide that into the actual total 21, to get 3

then multiply 3 by 2 and 5 to get 6:15

Answer 5
