Answer 1

Answer:

The sum of these natural numbers is 162

Explanation:

According to the question , The ratio of 2 natural numbers is 4:5 and their LCM is 360.

LCM is least common multiple . Least common multiple is a process by which we find out the smallest common multiple between two or more numbers.

Let the number are 4x and 5x.

So, the LCM is 20x.

According to the question ,

$20x = 360\\or , x = 18.$

So the numbers are $4*18 =72$ and $5*18 =90$

The sum of these natural numbers is  $72+90 = 162$
