Question

Fresh apples float because 1/4 of their weight is air. If a bag of apples weighs 2 1/2 pounds, how many pounds is air?

Answer 1

0, Air is weightless.

Answer 2

In
`2(1)/(2)` pounds of apple there are
`(5)/(8)` Pounds of air.

Explanation:

If you take an apple that weighs 1 pound then weight of air inside that apple is
`(1)/(4)` pounds.

If 1 pound of apple has
`(1)/(4)` pounds of air then how much air is in
`2(1)/(2)` pounds of apple?

`\frac{(1)/(4)} {1} *2(1)/(2)`

`(1)/(4) *(5)/(2)`

`(5)/(8)` Pounds of air.

So in
`2(1)/(2)` pounds of apple there are
`(5)/(8)` Pounds of air.
