Answer: 241.6 is 60 2/5% of 400.
Explanation:
The way we go about this is with these fractions setup like this:
Part Percent
____ x ____
Whole 100
Now we need to add in what we know. The 100 will always be there, you can do that every time. We know the part, (241.6) and the percent (60 2/5%) and we're looking for the whole.
241.6 60 2/5%
____ x ____
? 100
Now we look the diagonals. Our diagonals are 241.6 and 100, and 60 2/5% and ?. We'll take the one that DOESN'T have the question mark in it, and multiply those.
241.6 x 100 = 24,160
And then we take whatever number is left (that isn't the ?) and divide that by whatever number is left
24,160 / 60.4 = 400
Therefore, your whole is 400.
