If 40% of a number is 56, what was the original number?
0.40 x = 56
x = 56/.4 = 560/4
the best message I can give to you is this: is over of is equal to percent over 100. the number after is is 56 and the percent is 40. so you put 56/x and set that equal to 40/100 which simplifies to 2/5
cross multiply the two: 56 * 5 and 2 * x
write the equation 280 = 2x
Divide: 280 / 2 = 140
I know this won't help with the specific problem you were having trouble with, but if you ever see a problem with IF, OF AND A PERCENT use this method.
Hope this helps you in the future
just do 56/x=40/100 which can be simplified to 56/x=2/5. 56*5=280 and x*2=2x so 280/2 is 140
280/2 is 140
