Answer 1

I don’t actually know I’m just trying to get points

Answer 2

B

Explanation:

The number
`a . 10^(-2)` is 8 times greater than
`b . 10^(-3)`

thus,
`a . 10^(-2) = 8b. 10^(-3)`

multiply both sides by
`10^(2)`

we get
`a = 8b. 10^(-1) \\a = 0.8 b`

if we take a = 2.5 and b = 3.1 we get 2.5/3.1 = 0.8

then B is the answer
