3.43 is what percent of 4.9 - 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 4.9 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 100% equals 4.9, so we can write it down as 100%=4.9.
4. We know, that x% equals 3.43 of the output value, so we can write it down as x%=3.43.
5. Now we have two simple equations:
1) 100%=4.9
2) x%=3.43
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%=4.9/3.43
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.43 is what percent of 4.9

100%/x%=4.9/3.43
(100/x)*x=(4.9/3.43)*x       - we multiply both sides of the equation by x
100=1.4285714285714*x       - we divide both sides of the equation by (1.4285714285714) to get x
100/1.4285714285714=x
70=x
x=70

now we have:
3.43 is 70% of 4.9
