Breaking down the problem:
First, let’s break down each piece of the problem. We have the fraction, 21/2, which is also the dividend, and the whole number, or the divisor, which is 3:
Numerator of the dividend: 21
Denominator of the dividend: 2
Whole number and divisor: 3
So what is 21/2 Divided by 3? Let’s work through the problem, and find the answer in both fraction and decimal forms.
What is 21/2 Divided by 3, Step-by-step from a math tutor
First let’s set up the problem:
Step 1:
Take the whole number, 3, and multiply it by the denominator of the fraction, 2:
