1.4 is what percent of 7.4 - 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 7.4 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 7.4, so we can write it down as 100%=7.4.
4. We know, that x% equals 1.4 of the output value, so we can write it down as x%=1.4.
5. Now we have two simple equations:
1) 100%=7.4
2) x%=1.4
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%=7.4/1.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.4 is what percent of 7.4

100%/x%=7.4/1.4
(100/x)*x=(7.4/1.4)*x       - we multiply both sides of the equation by x
100=5.28571428571*x       - we divide both sides of the equation by (5.28571428571) to get x
100/5.28571428571=x
18.9189189189=x
x=18.9189189189

now we have:
1.4 is 18.9189189189% of 7.4
