Answer: 17.5%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.
So to write 7/40 as a percent, we need to find a fraction equivalent to 7/40 that has a 100 in the denominator.
We can do this by setting up a proportion.
Now we can use cross products to find the missing value.
=
700 = 40n
Next, dividing both sides of the equation by 40, we have <em>17.5 = n</em>.
So, 7/40 is equal to 17.5/100 or 17.5%.
