In a box there are 145 apples.
Some of the apples are red and the rest are green.
The ratio of red to green apples is 2:3
How many green apples are there?

87 green apples

Step-by-step explanation:

Red apples  : green apples = 2 : 3

Number of red apples = 2x

Number of green apples = 3x

Total apples = 145

3x + 2x = 145

5x = 145

x = 145/5

x = 29

Number of green apples = 3x = 3 * 29 = 87
