First, let’s break down each piece of the problem. We have the fraction, 40/31, which is also the dividend, and the whole number, or the divisor, which is 90:
Numerator of the dividend: 40
Denominator of the dividend: 31
Whole number and divisor: 90
So what is 40/31 Divided by 90? 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, 90, and multiply it by the denominator of the fraction, 31:
31 x 90 = 2790
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 40/31 Divided by 90 in decimal form, you can divide the numerator, 2790, by the denominator, 40. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 40 divided by 31/90 = 69.75
And in its simplest fractional form, 40 divided by 31/90 is 279/4
