First, let’s break down each piece of the problem. We have the fraction, 21/79, which is also the dividend, and the whole number, or the divisor, which is 7:
Numerator of the dividend: 21
Denominator of the dividend: 79
Whole number and divisor: 7
So what is 21/79 Divided by 7? 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, 7, and multiply it by the denominator of the fraction, 79:
79 x 7 = 553
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 21/79 Divided by 7 in decimal form, you can divide the numerator, 553, by the denominator, 21. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 21 divided by 79/7 = 26.33
And in its simplest fractional form, 21 divided by 79/7 is 79/3
