Calculate unit rates to solve each problem.
1. cara can run 3 miles in 27 minutes. melanie can run
6 miles in 53 minutes. who can run faster?
let c represent cara's speed and m represent melanie's speed.
equivalent ratio i: .
equivalent ratio 2:
can run faster.
how runs more in confused?

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
