What is 62.1 percent of 70 - 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 70 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 70 is 100%, so we can write it down as 70=100%.
4. We know, that x is 62.1% of the output value, so we can write it down as x=62.1%.
5. Now we have two simple equations:
1) 70=100%
2) x=62.1%
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:
70/x=100%/62.1%
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 62.1% of 70

70/x=100/62.1
(70/x)*x=(100/62.1)*x       - we multiply both sides of the equation by x
70=1.610305958132*x       - we divide both sides of the equation by (1.610305958132) to get x
70/1.610305958132=x
43.47=x
x=43.47

now we have:
62.1% of 70=43.47
