Answer:
60 blueberries
Explanation:
Given the ratio of blueberries to strawberries in a fruit salad to be 4:3. The total ratio = 4+3 = 7
If there are 45 strawberries in the salad then we can first calculate the total mixture of both as shown;
amount of strawberries = 3/7 * x = 45
x is the total amount of mixture
from the expression;
3x/7 = 45
cross multiply
3x = 7*45
3x = 315
x = 315/3
x = 105
The amount of blueberries present = 105 - 45 = 60
Hence the amount of blueberries present is 60 blueberries
