Question

The sum of two numbers is 18. if the larger number is 4 times the smaller number, what are the two numbers?

Answer 1

The sum of two numbers is 18. If the largest number is four times the smaller number, the two numbers are 6 and 12.

Answer 2

Answer: 3.6 and 14.4

Explanation:

Let x be the smaller number because it can be used to find the larger one, through the question stating that it is 4 times smaller than the larger one.

This leads us to this equation:

4x + x = 18.

4x represents the larger number. Now, simplify and solve.

5x=18

Divide 18 by 5.

x=3.6.

Now that we know that the smaller number is 3.6, we automatically know that the larger number is 14.4 (3.6 multiplied by 4).

Add them together to check: 3.6+14.4=18.
