Answer:
5x = 45, 3x = 27
Step-by-step explanation:
Let us take 5:3 as 5x and 3x
=> 5x - 3x = 18
=> 2x = 18
=> x = 18/2
=> x = 9
Therefore, 5x = 5x9 = 45
3x = 3x9 = 27

Given:
2 numbers are in the ratio of 5:3.
Their difference is 18.
We are supposed to find the numbers.
Solution:
Let us assume the 2 numbers to be x and y.
From what is given,
1. x/y = 5/3.
2. x - y = 18.
From 1.
x = 5y/3. - Substitute this in 2.
5y/3 - y = 18.
(5y - 3y)/3 = 18. (Taking LCM)
2y = 54.
y = 27.
x = 5(27)/3 = 5(9) = 45.
x = 45.
Therefore, the numbers are 45 and 27.
Answer: 45, 27.
