70 is what percent of 1356 - 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 1356 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 1356, so we can write it down as 100%=1356.
4. We know, that x% equals 70 of the output value, so we can write it down as x%=70.
5. Now we have two simple equations:
1) 100%=1356
2) x%=70
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:
100%/x%=1356/70
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 70 is what percent of 1356

100%/x%=1356/70
(100/x)*x=(1356/70)*x       - we multiply both sides of the equation by x
100=19.371428571429*x       - we divide both sides of the equation by (19.371428571429) to get x
100/19.371428571429=x
5.1622418879056=x
x=5.1622418879056

now we have:
70 is 5.1622418879056% of 1356
