Answer:
704
Step-by-step explanation:
1. We assume, that the number 550 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 550 is 100%, so we can write it down as 550=100%.
4. We know, that x is 128% of the output value, so we can write it down as x=128%.
5. Now we have two simple equations:
1) 550=100%
2) x=128%
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:
550/x=100%/128%
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 128% of 550
550/x=100/128
(550/x)*x=(100/128)*x - we multiply both sides of the equation by x
550=0.78125*x - we divide both sides of the equation by (0.78125) to get x
550/0.78125=x
704=x
x=704
now we have:
128% of 550=704
