First, let’s break down each piece of the problem. We have the fraction, 78/90, which is also the dividend, and the whole number, or the divisor, which is 64:
Numerator of the dividend: 78
Denominator of the dividend: 90
Whole number and divisor: 64
So what is 78/90 Divided by 64? 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, 64, and multiply it by the denominator of the fraction, 90:
90 x 64 = 5760
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 78/90 Divided by 64 in decimal form, you can divide the numerator, 5760, by the denominator, 78. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 78 divided by 90/64 = 73.85
And in its simplest fractional form, 78 divided by 90/64 is 960/13
