Answer:
118%
Step-by-step explanation:
The kitten's initial weight was 550 grams. Subtracting that from its current weight, 1200 grams, we see that the weight gain was 650 grams.
This increase, divided by the initial weight, comes out to
650 grams
------------------ = 1.1818
550 grams
As a percentage, rounded off to the nearest whole number, the kitten's increase in weight was 118%.
