jek_recluse [69]

Answer:

The mom ate 49 fish.

Step-by-step explanation:

This question can be solved by a rule of three.

a mother otter is fed 7 fish for every 2 fish for its cub

if  a cub has eaten 14 fish , how many fish did the mother eat ?

For each 2 fish cub eats, the mon eats 7. How much has the mom eaten if the cub has eaten 14?

So

2 - 7

14 - x

2x = 14*7

Simplifying by 2

x = 7*7

x = 49

The mom ate 49 fish.
