Answer:
90 : 135 : 225
Explanation:
sum the parts of the ratio, 2 + 3 + 5 = 10 parts
Divide the number by 10 to find the value of one part of the ratio
450 ÷ 10 = 45 ← value of 1 part of the ratio, then
2 parts = 2 × 45 = 90
3 parts = 3 × 45 = 135
5 parts = 5 × 45 = 225
Then
450 in the ratio 2 : 3 : 5 is 90 : 135 : 225
