What is 142 percent of 978.9 - 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 978.9 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 978.9 is 100%, so we can write it down as 978.9=100%.
4. We know, that x is 142% of the output value, so we can write it down as x=142%.
5. Now we have two simple equations:
1) 978.9=100%
2) x=142%
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:
978.9/x=100%/142%
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 142% of 978.9

978.9/x=100/142
(978.9/x)*x=(100/142)*x       - we multiply both sides of the equation by x
978.9=0.70422535211268*x       - we divide both sides of the equation by (0.70422535211268) to get x
978.9/0.70422535211268=x
1390.038=x
x=1390.038

now we have:
142% of 978.9=1390.038
