Question

The ratio of dolphins to whales sighted on a boat tour was 8 to 2. If there were 22 whales sighted, how many dolphins were sighted? Complete the ratio table to find the number of dolphins.

Answer 1

88

Explanation:

Dolphins to whales=8:2

8/10 represent x

Cross multiplying

`x=\frac {22* 8/10}{2/10}=88`
