First, let’s break down each piece of the problem. We have the fraction, 8/20, which is also the dividend, and the whole number, or the divisor, which is 45:
Numerator of the dividend: 8
Denominator of the dividend: 20
Whole number and divisor: 45
So what is 8/20 Divided by 45? 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, 45, and multiply it by the denominator of the fraction, 20:
20 x 45 = 900
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 8/20 Divided by 45 in decimal form, you can divide the numerator, 900, by the denominator, 8. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 8 divided by 20/45 = 112.5
And in its simplest fractional form, 8 divided by 20/45 is 225/2
