First, let’s break down each piece of the problem. We have the fraction, 42/17, which is also the dividend, and the whole number, or the divisor, which is 20:
Numerator of the dividend: 42
Denominator of the dividend: 17
Whole number and divisor: 20
So what is 42/17 Divided by 20? 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, 20, and multiply it by the denominator of the fraction, 17:
17 x 20 = 340
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 42/17 Divided by 20 in decimal form, you can divide the numerator, 340, by the denominator, 42. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 42 divided by 17/20 = 8.1
And in its simplest fractional form, 42 divided by 17/20 is 170/21
