Question

A hippopotamus had a mass of 33.8 kg at birth. At two months old, it had a mass of 89.3 kg. By what percentage did its mass increase over these two months? Give your answer to the nearest 1%.​

Answer 1

The hippopotamus' mass increased by approximately 164% over the two-month period.

Step-by-step explanation:

To calculate the percentage increase in mass, we need to find the difference between the final mass and the initial mass, then divide that by the initial mass and multiply by 100.

The initial mass was 33.8 kg and the final mass was 89.3 kg.

The difference between the two masses is 89.3 kg - 33.8 kg = 55.5 kg.

To find the percentage increase, we divide the difference by the initial mass and multiply by 100: (55.5 kg / 33.8 kg) x 100 = 164.02%.
