Math Tutor's Solution to What is 5/15 Divided by 21?
Methods
Breaking down the problem:
First, let’s break down each piece of the problem. We have the fraction, 5/15, which is also the dividend, and the whole number, or the divisor, which is 21:
Numerator of the dividend: 5
Denominator of the dividend: 15
Whole number and divisor: 21
So, what is 5/15 Divided by 21? Let’s work through the problem and find the answer in both fraction and decimal forms.
What is 5/15 Divided by 21, Step-by-step from Math Tutor
First let’s set up the problem:
Step 1:
The first step of this solution is to multiple the denominator of the dividend, 15, by the whole number 21:
15 x 21 = 315
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:
315/5 = 63/1
A fraction that has 1 as its denominator is an improper fraction. So, we should simplify this to just the numerator. Since the numerator is a whole number, there is no reason to write the answer in decimal form.
So, 5 divided by 15/21 = 63
