Question

7/40=(7/40×100)%=35/2%=17.5 how​

Answer 1

Answer:

Before we get started in the fraction to percentage conversion, let's go over some very quick fraction basics. Remember that a numerator is the number above the fraction line, and the denominator is the number below the fraction line. We'll use this later in the tutorial.

When we are using percentages, what we are really saying is that the percentage is a fraction of 100. "Percent" means per hundred, and so 50% is the same as saying 50/100 or 5/10 in fraction form.

So, since our denominator in 7/40 is 40, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:

100 ÷ 40 = 2.5

Once we have that, we can multiple both the numerator and denominator by this multiple:

7 x 2.5

40 x 2.5

=

17.5

100

Now we can see that our fraction is 17.5/100, which means that 7/40 as a percentage is 17.5%.

We can also work this out in a simpler way by first converting the fraction 7/40 to a decimal. To do that, we simply divide the numerator by the denominator:

7/40 = 0.175

Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:

0.175 x 100 = 17.5%

And there you have it! Two different ways to convert 7/40 to a percentage. Both are pretty straightforward and easy to do, but I personally prefer the convert to decimal method as it takes less steps.
