Question

1. select all that apply. which is an accurate way to compare the numbers a = 0.000054 and b = 0.0027? a is twice as small as b. a is b times 0.02. a is 2×10² times b. a is 2×10⁻² times b. a is twice as large as b.

Explanation:

Step1: Calculate the ratio of A to B

$r=\frac{A}{B}=\frac{0.000054}{0.0027}$

Step2: Simplify the ratio

$r = 0.02=2\times10^{-2}$

Answer:

A is B times 0.02.
A is $2\times 10^{-2}$ times B.
