Answer to Problem 26CCR
17 is 85% of 20
Explanation of Solution
Given: Find 17 is what percent of 20?
Concept Used:
Let the required percent is x
Calculation:
1. We assume that the number 20 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 20, so we can write it down as 100% = 115.
4. We know, that x% equals 17 of the output value, so we can write it down as x% = 17.
5. Now we can set a Proportion with same units and solve for x
Thus, 17 is 85 % of 20.
