First, let’s break down each piece of the problem. We have the fraction, 87/21, which is also the dividend, and the whole number, or the divisor, which is 12:
Numerator of the dividend: 87
Denominator of the dividend: 21
Whole number and divisor: 12
So what is 87/21 Divided by 12? 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, 12, and multiply it by the denominator of the fraction, 21:
21 x 12 = 252
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 87/21 Divided by 12 in decimal form, you can divide the numerator, 252, by the denominator, 87. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 87 divided by 21/12 = 2.9
And in its simplest fractional form, 87 divided by 21/12 is 84/29
