What is 79 percent of 89.71 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 89.71 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 89.71 is 100%, so we can write it down as 89.71=100%.
4. We know, that x is 79% of the output value, so we can write it down as x=79%.
5. Now we have two simple equations:
1) 89.71=100%
2) x=79%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
89.71/x=100%/79%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 79% of 89.71

89.71/x=100/79
(89.71/x)*x=(100/79)*x       - we multiply both sides of the equation by x
89.71=1.2658227848101*x       - we divide both sides of the equation by (1.2658227848101) to get x
89.71/1.2658227848101=x
70.8709=x
x=70.8709

now we have:
79% of 89.71=70.8709
