Math Tutor's Solution to What is 18/20 Divided by 81?
Methods
Breaking down the problem:
First, let’s break down each piece of the problem. We have the fraction, 18/20, which is also the dividend, and the whole number, or the divisor, which is 81:
Numerator of the dividend: 18
Denominator of the dividend: 20
Whole number and divisor: 81
So, what is 18/20 Divided by 81? Let’s work through the problem and find the answer in both fraction and decimal forms.
What is 18/20 Divided by 81, 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, 20, by the whole number 81:
20 x 81 = 1620
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:
1620/18 = 90/1
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, 18 divided by 20/81 = 90
