Question

Elena is conduction 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 Elena’s survey, what is the ratio of male fish with egg cells to male cells in the river?

Answer 1

3:7

Step-by-step explanation:

We know that Elena surveys 350 male fish in a river.

Out of these 350 fish, 150 have egg cells growing inside them.

Therefore,

male fish with egg cells: male fish in the river = 150: 350

The next step is to write this ratio as a fraction and simplify it.

Writing the ratio as a fraction gives

`(150)/(350)`

dividing both the numerator and the denominator by 50 gives

`(150/50)/(350/50)`
`=(3)/(7)`

Hence, the ratio of the male fish with egg cells to total male fish in the river is 3:7.
