Question

A single Rhinovirus is 2 × 10^-8 meters long, and a single E. coli bacterium is 2 × 10^-6 meters long. How many times larger is an E. coli bacterium than a Rhinovirus?

Answer 1

Explanation:

Start off by dividing (2×10^-6)÷(2×10^-8)= 100

Then you move to decimal over 2 places to get you final answer of

1×10^2

Answer 2

100 times larger

Explanation:

A single Rhinovirus = 2 * (10^(-8)) meters = 2 x 10^-5 millimeters = 0.00002 millimeters (as -3 = -3 zeros) Where a single E. coli bacterium = 2 * (10^(-6)) meters = 0.002 millimeters Then we divide = 0.002 / 0.00002 = 100
