Answer:
118%
Step-by-step explanation:
The kitten's initial weight was 550 grams. Â 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%.
