First, let’s break down each piece of the problem. We have the fraction, 86/90, which is also the dividend, and the whole number, or the divisor, which is 72:
Numerator of the dividend: 86
Denominator of the dividend: 90
Whole number and divisor: 72
So what is 86/90 Divided by 72? 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, 72, and multiply it by the denominator of the fraction, 90:
90 x 72 = 6480
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 86/90 Divided by 72 in decimal form, you can divide the numerator, 6480, by the denominator, 86. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 86 divided by 90/72 = 75.35
And in its simplest fractional form, 86 divided by 90/72 is 3240/43
