1.21 is what percent of 40.98 - 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 40.98 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 40.98, so we can write it down as 100%=40.98.
4. We know, that x% equals 1.21 of the output value, so we can write it down as x%=1.21.
5. Now we have two simple equations:
1) 100%=40.98
2) x%=1.21
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%=40.98/1.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.21 is what percent of 40.98

100%/x%=40.98/1.21
(100/x)*x=(40.98/1.21)*x       - we multiply both sides of the equation by x
100=33.867768595041*x       - we divide both sides of the equation by (33.867768595041) to get x
100/33.867768595041=x
2.9526598340654=x
x=2.9526598340654

now we have:
1.21 is 2.9526598340654% of 40.98
