First, let’s break down each piece of the problem. We have the fraction, 8/20, which is also the dividend, and the whole number, or the divisor, which is 21:
Numerator of the dividend: 8
Denominator of the dividend: 20
Whole number and divisor: 21
So what is 8/20 Divided by 21? Let’s work through the problem, and find the answer in both fraction and decimal forms.
First let’s set up the problem:
Step 1:
Take the whole number, 21, and multiply it by the denominator of the fraction, 20:
20 x 21 = 420
Step 2:
The result of this multiplication will now become the denominator of the answer. The answer to the problem in fraction form can now be seen:
To display the answer to 8/20 Divided by 21 in decimal form, you can divide the numerator, 420, by the denominator, 8. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 8 divided by 20/21 = 52.5
And in its simplest fractional form, 8 divided by 20/21 is 105/2
