What multiplied by what will give you 120?

Answer 1

If you don't mind fractions and decimals, then there are an infinite number of pairs

whose product is 120.

If you only want to talk about whole numbers, then here are the possibilities:

1 x 120

2 x 60

3 x 40

4 x 30

5 x 24

6 x 20

8 x 15

10 x 12

and 8 more that look the same as those 8 but with all negative numbers.
