The sum of the two numbers is 180. The ratio of these numbers is 5: 4. What is each of these numbers equal to?

To find the numbers, we first count the total number of parts of those numbers. To do this, add five and four.
1) 5 + 4 = 9.
2) Now we will find one part of each number. For this 180: 9 = 20.
The first number has five parts, and the second has four. Now let’s multiply:
3) 5 * 20 = 100.
4) 4 * 20 = 80.
Let’s check the received numbers so that they add up to 180.
100 + 80 = 180. It all came together.
Answer: the first number is 100, the second number is 80.
