Question

How many times smaller is 5×10-7 than 8.5×10-4

Answer 1

About 5 times per size

Answer 2

Approximately 1.86 times smaller

Explanation:

5×10-7 = (5×10=50) = 50-7 = 43

8.5×10-4 = (8.5×10=84) = 84- 4 = 80

80/43 = approximately 1.86

43×1.86 = approximately 80

80/1.86 = approximately 43
