Question

ratios, rates, and proportions: medium
elena is conducting a study about the effects of toxins in the water on the hormones of fish. elena surveys 350 male fish in a river and finds that 150 of the male fish have egg cells growing inside them. according to elenas survey, what is the ratio of male fish with egg cells to male fish without egg cells in the river?
choose 1 answer:
a 3:4
b 3:7
c 4:5
d 4:7

Explanation:

Step1: Calculate male fish without egg cells

The number of male - fish without egg cells is \(350 - 150=200\).

Step2: Find the ratio

The ratio of male fish with egg cells to male fish without egg cells is \(\frac{150}{200}\). Simplify the ratio \(\frac{150\div50}{200\div50}=\frac{3}{4}\), which is \(3:4\).

Answer:

A. \(3:4\)
