3/8ths =0.375 = 37.5%
A plant every 1.7 feet.
9/20 is the simplest form of this fraction. Goldfish and Marbles aren't really comparable unless the goldfish is equivalent to a certain number of marbles. Say the Goldfish cost x and the marbles cost y, a goldfish is then x/y marbles so the answer is 9x/20y. As I don't know x or y, you'll have to simplify that yourself.
Write 171 miles in 3 hour as a unit rate

You divide it by 4.5 and then put it as a fraction
102 miles to 4 minute = 51 miles to 2 minutes
Write 171 miles in 3 hour as a unit rate
Find an equivalent ratio so that the denominator = 1. This may require the numerator to be a fraction.
the same as a unit rate just in fraction form
