Methods
Breaking down the problem:
First, let’s break down each piece of the problem. We have the fraction, 2/5, which is also the dividend, and the whole number, or the divisor, which is 21:
Numerator of the dividend: 2
Denominator of the dividend: 5
Whole number and divisor: 21
So what is 2/5 Divided by 21? Let’s work through the problem, and find the answer in both fraction and decimal forms.
What is 2/5 Divided by 21, Step-by-step from a math tutor
First let’s set up the problem:
Step 1:
Take the whole number, 21, and multiply it by the denominator of the fraction, 5:
5 x 21 = 105
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 2/5 Divided by 21 in decimal form, you can divide the numerator, 105, by the denominator, 2. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 2 divided by 5/21 = 52.5
And in its simplest fractional form, 2 divided by 5/21 is 105/2
