If 3x : 2y = 6 : 5, what is the ratio of x and y?
If 3x : 2y = 6 : 5, what is the ratio of x and y?
Explanation
Given:
3x : 2y = 6 : 5
Cross-multiply:
(3x) × 5 = (2y) × 6
15x = 12y
Divide both sides by 3y:
5x/y = 4
x/y = 4/5
So, x : y = 4 : 5
Given:
3x : 2y = 6 : 5
Cross-multiply:
(3x) × 5 = (2y) × 6
15x = 12y
Divide both sides by 3y:
5x/y = 4
x/y = 4/5
So, x : y = 4 : 5
