First, let’s break down each piece of the problem. We have the fraction, 15/8, which is also the dividend, and the whole number, or the divisor, which is 81:
Numerator of the dividend: 15
Denominator of the dividend: 8
Whole number and divisor: 81
So what is 15/8 Divided by 81? 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, 81, and multiply it by the denominator of the fraction, 8:
8 x 81 = 648
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 15/8 Divided by 81 in decimal form, you can divide the numerator, 648, by the denominator, 15. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 15 divided by 8/81 = 43.2
And in its simplest fractional form, 15 divided by 8/81 is 216/5
