What is 210 percent of 357 - 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 357 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 357 is 100%, so we can write it down as 357=100%.
4. We know, that x is 210% of the output value, so we can write it down as x=210%.
5. Now we have two simple equations:
1) 357=100%
2) x=210%
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:
357/x=100%/210%
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 210% of 357

357/x=100/210
(357/x)*x=(100/210)*x       - we multiply both sides of the equation by x
357=0.47619047619048*x       - we divide both sides of the equation by (0.47619047619048) to get x
357/0.47619047619048=x
749.7=x
x=749.7

now we have:
210% of 357=749.7
