First, let’s break down each piece of the problem. We have the fraction, 12/9, which is also the dividend, and the whole number, or the divisor, which is 45:
Numerator of the dividend: 12
Denominator of the dividend: 9
Whole number and divisor: 45
So what is 12/9 Divided by 45? 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, 45, and multiply it by the denominator of the fraction, 9:
9 x 45 = 405
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 12/9 Divided by 45 in decimal form, you can divide the numerator, 405, by the denominator, 12. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 12 divided by 9/45 = 33.75
And in its simplest fractional form, 12 divided by 9/45 is 135/4
