Question

there are 1505 fruits for sale at a Farmers Market 39% of them are apples 28% are oranges 13% are honeydew melons and the rest are watermelons how many watermelons are there

Answer 1

100% - (39% + 28% + 13%) = 100% - 80% = 20%
so 20% are watermelons.

20% of 1505...
0.20(1505) = 301

so 301 are watermelons
