1.4 is what percent of 220 - 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 220 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 220, so we can write it down as 100%=220.
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%=220
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%=220/1.4
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 220

100%/x%=220/1.4
(100/x)*x=(220/1.4)*x       - we multiply both sides of the equation by x
100=157.14285714286*x       - we divide both sides of the equation by (157.14285714286) to get x
100/157.14285714286=x
0.63636363636364=x
x=0.63636363636364

now we have:
1.4 is 0.63636363636364% of 220
