The sum of two numbers is 26.4. One is five times the other. Find the numbers

Let the first number be x

The other number is 5x because we are told one is 5times the other

The sum x+5x = 26.4

6x=26.4

x = 26.4/6

x=4.4 (first number)

second number = 5x but we now know x = 4.4

second number = 5*4.4 = 22

So your two numbers are 4.4 and 22

To prove you can add them

Let the first number be x

The other number is 5x because we are told one is 5times the other

The sum x+5x = 26.4

6x=26.4

x = 26.4/6

x=4.4 (first number)

second number = 5x but we now know x = 4.4

second number = 5*4.4 = 22
