First, let’s break down each piece of the problem. We have the fraction, 78/7, which is also the dividend, and the whole number, or the divisor, which is 18:
Numerator of the dividend: 78
Denominator of the dividend: 7
Whole number and divisor: 18
So what is 78/7 Divided by 18? 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, 18, and multiply it by the denominator of the fraction, 7:
7 x 18 = 126
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 78/7 Divided by 18 in decimal form, you can divide the numerator, 126, by the denominator, 78. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 78 divided by 7/18 = 1.62
And in its simplest fractional form, 78 divided by 7/18 is 21/13
