Find the sum of three numbers if one of them is 26.1 and it is 3/5 of the second, and the third is 60% of the second.

To solve this task, remember, in order to find the number by its part, expressed as a fraction, you need to divide this number by a fraction. Let’s calculate what the second number is.

26.1: 3/5 = 26.1 * 5/3 = 130.5 / 3 = 43.5.

Let’s calculate what the third number is. To find the percentage of the number, you need to multiply this number by the percentage and divide by one hundred.

43.5 * 60/100 = 43.5 * 0.6 = 26.1.

Let’s calculate what the sum of three numbers is equal to.

43.5 + 26.1 + 26.1 = 95.7.

Answer: 95.7.
