75 is what percent of 1340 - 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 1340 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 1340, so we can write it down as 100%=1340.
4. We know, that x% equals 75 of the output value, so we can write it down as x%=75.
5. Now we have two simple equations:
1) 100%=1340
2) x%=75
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%=1340/75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 75 is what percent of 1340

100%/x%=1340/75
(100/x)*x=(1340/75)*x       - we multiply both sides of the equation by x
100=17.866666666667*x       - we divide both sides of the equation by (17.866666666667) to get x
100/17.866666666667=x
5.5970149253731=x
x=5.5970149253731

now we have:
75 is 5.5970149253731% of 1340
