What is 68.9 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 68.9% of the output value, so we can write it down as x=68.9%.
5. Now we have two simple equations:
1) 70=100%
2) x=68.9%
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%/68.9%
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 68.9% of 70

70/x=100/68.9
(70/x)*x=(100/68.9)*x       - we multiply both sides of the equation by x
70=1.4513788098694*x       - we divide both sides of the equation by (1.4513788098694) to get x
70/1.4513788098694=x
48.23=x
x=48.23

now we have:
68.9% of 70=48.23
