How do you write 160000 and 1000000 as a ratio in lowest terms?

Answer 1

160000/1000000

The easiest first step is to remove corresponding zeros:

160000/1000000 = 16/100

Both 16 and 100 are divisible by 4, so divide the numerator and denominator by 4:

16/100 ÷ 4/4 = 4/25

This is the ratio in lowest terms.
