Question

The weight of a boy was 15kg last year. If his weight increases by 3kg this year, find the percentage increase in his weight.

Answer 1

This year = 18kg
18 x .3= 5.4
The percentage change would be 5.4%. If it needs to be rounded by the nearest tenth, then it would be 5%.
I’m pretty confident this is the answer but I’m not 100% sure. I hope this helps!
