Answer 1

b) 36.

Explanation:

Justicemoya35 has an excellent answer, but I will provide a slightly different approach!

According to the word problem, the box contains 60 apples.

If 40% of the apples are red, then 60% of the apples are green.

As I mentioned before, there are 60 apples; 60% of the 60 apples are green.

This means we have the find 60% of 60.

We can find the percentage of a number by using this formula:

60% OF 60

`(is)/(of) =(percent)/(100)`

`(x)/(60) =(60)/(100)`

Now that I've correctly set up the problem, we cross multiply, then divide the products.

`60*60=3600`

`100*x=100x`

`3600/100x=36`

`x=36.`

Therefore, 36 apples are red.

Answer 2

36 green apples

Explanation:

Red=40%

Green =x%

40/100 × 60apples

0.4×60

24red apples

so 60-24
