A panther cub weighs 890 grams. At birth the cub weighed 450 grams. What is the percent increase in the panther cub's weight rounded to the nearest whole number?
First subtract the birth weight from the new weight (890-450=440). To find what percent of 450 that is, divide the difference by 450 (440/450=97.78). Round to the nearest whole number (97.78==>98).
