What is 74 percent of 42.3 - 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 42.3 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 42.3 is 100%, so we can write it down as 42.3=100%.
4. We know, that x is 74% of the output value, so we can write it down as x=74%.
5. Now we have two simple equations:
1) 42.3=100%
2) x=74%
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:
42.3/x=100%/74%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 74% of 42.3

42.3/x=100/74
(42.3/x)*x=(100/74)*x       - we multiply both sides of the equation by x
42.3=1.3513513513514*x       - we divide both sides of the equation by (1.3513513513514) to get x
42.3/1.3513513513514=x
31.302=x
x=31.302

now we have:
74% of 42.3=31.302
