First, let’s break down each piece of the problem. We have the fraction, 12/13, which is also the dividend, and the whole number, or the divisor, which is 31:
Numerator of the dividend: 12
Denominator of the dividend: 13
Whole number and divisor: 31
So what is 12/13 Divided by 31? 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, 31, and multiply it by the denominator of the fraction, 13:
13 x 31 = 403
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 12/13 Divided by 31 in decimal form, you can divide the numerator, 403, by the denominator, 12. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 12 divided by 13/31 = 33.58
And in its simplest fractional form, 12 divided by 13/31 is 403/12
