Answer: Therefore, there are 50 red apples.
Explanation:
If the ratio of green apples to red apples is 2:5, this means that for every 2 green apples, there are 5 red apples.
We are given that there are 20 green apples, so we can use this to find the number of red apples.
First, we need to find out how many sets of 2 green apples there are in 20 green apples. We can do this by dividing 20 by 2:
20 ÷ 2 = 10
This means there are 10 sets of 2 green apples in 20 green apples.
Since there are 5 red apples for every 2 green apples, we need to multiply the number of sets of 2 green apples by 5 to find the number of red apples:
10 x 5 = 50
