21 is what percent of 700358 - 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 700358 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 700358, so we can write it down as 100%=700358.
4. We know, that x% equals 21 of the output value, so we can write it down as x%=21.
5. Now we have two simple equations:
1) 100%=700358
2) x%=21
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%=700358/21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21 is what percent of 700358

100%/x%=700358/21
(100/x)*x=(700358/21)*x       - we multiply both sides of the equation by x
100=33350.380952381*x       - we divide both sides of the equation by (33350.380952381) to get x
100/33350.380952381=x
0.0029984664985622=x
x=0.0029984664985622

now we have:
