please mark as brainlist...!!

Step-by-step explanation:

Given Ratio is 2 : 5

Let the first number is 2x and the other is 5x. their difference is 27,

So, 5x - 2x = 27

=> 3x = 27

Divide both sides by 3, we get

x = 9

So two numbers are

2x =2 X 9 = 18

and

5x = 5 X 9= 45

Check your answer

45 - 18 = 27

and 18/45 = 2 / 5

=> 2 : 5

So, the Larger number is 45 Answer
