Enter fraction(s) below:

Simplify and Evaluate the following fraction:

15
20

First, evaluate the numerator and denominator

The numerator is 15
The denominator is 20

Reduce our fraction

GCF(15 and 20) = 5

Reduce the numerator by GCF

(1/5) x 15 = 3

Reduce the denominator by GCF

(1/5) x 20 = 4

You entered a fraction. We need to convert this fraction number to a mixed number.
Let's find the whole number first. The formula for this is:
(Numerator/Denominator) in whole numbers

Using the fraction you entered of 15/20, let's evaluate:
Whole Number = 15 / 20 = 0.75
Whole Number = Integer(0.75)
Whole Number = 0

Now we find the fractional portion of the mixed number. The formula for that is:

(Numerator - Denominator x Whole Number)
Denominator

Using the values we entered and calculated, we get:

Fraction Portion =	(15 - 20 x 0)
	20

Fraction Portion =	15 - 0
	20

Fraction Portion =	15
	20

Now combine both pieces and piece together the mixed number:
Mixed Number = Whole Number & fraction Portion
Mixed Number = 0 & 15/20

What is the Answer?

3/4
