55 is 40 percent of what number

55 = 40%

x = 100%

x = (55x100) ÷ 40

x = 137.5

How do you find the answer to 50 percent of 70

To do this problem, you set up a proportion: 50 percent of 100 is equal to what (x) percent of 70? It should look like this:

50/100 = x/70

To solve this problem, divide 50 by 100:

.5 = x/70

To finish the equation, times both sides by 70:

(.5)(70) = (70)(x/70) [The x70 and /70 cancel each other out]

35 = x

So, 50% of 70 is 35.
