Question

Given that 2x/5 = 3y/8, find the ratio of x:y.

Answer 1

2x/5=3y/8
Cross multiply
(2x)(8)=(3y)(5)
16x=15y
•
• • x:y =16:15

Answer 2

`15:16`

Explanation:

`\textsf{We are given }\\\\(2x)/(5) = (3y)/(8)\\\\\textsf{Cross-multiply: }\\\\`

`2x * 8 = 3y * 5\\\\16x = 15y\\\\x = (15)/(16)y\\\\\\(x)/(y) = (15)/(16)\\\\This is just the ratio of x:y\textsf{Answer: } 15:16`
