Can you think of a different strategy to determine the ratio of 90 lbs on earth :15 lbs on the moon
Arlecino [84]

Given ratio : 90 lbs on earth :15 lbs on the moon.

Let us write 90 lbs :15 lbs in  fractions first.

90:15 = 90/15

Now, in order to determine different strategy, we need to find any equivalent fraction/ratio of the given fraction or ratio.

In order to find an equivalent fraction or ratio, we need to find a common number that can divide( even we can multiply) both numerator (top number) and denominator (bottom number).

For the given ratio 90/15, we can divide 90 and 15 both by 15.

90 ÷ 15 = 6

15 ÷ 15 = 1

Therefore, 90 lbs on earth :15 lbs on the moon could be written as 6 lbs on earth :1 lbs on the moon.
