First, let’s break down each piece of the problem. We have the fraction, 20/1, which is also the dividend, and the whole number, or the divisor, which is 42:
Numerator of the dividend: 20
Denominator of the dividend: 1
Whole number and divisor: 42
So what is 20/1 Divided by 42? 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, 42, and multiply it by the denominator of the fraction, 1:
1 x 42 = 42
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 20/1 Divided by 42 in decimal form, you can divide the numerator, 42, by the denominator, 20. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 20 divided by 1/42 = 2.1
And in its simplest fractional form, 20 divided by 1/42 is 21/10
