Answer:
250% of 354=885
Explanation:
We assume, that the number 354 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 354 is 100%, so we can write it down as 354=100%.
4. We know, that x is 250% of the output value, so we can write it down as x=250%.
5. Now we have two simple equations:
1) 354=100%
2) x=250%
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:
354/x=100%/250%
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 250% of 354
354/x=100/250
(354/x)*x=(100/250)*x - we multiply both sides of the equation by x
354=0.4*x - we divide both sides of the equation by (0.4) to get x
354/0.4=x
885=x
x=885
