Simplify and Evaluate the following fraction:
| 3 | |
| 21 |
First, evaluate the numerator and denominator
The numerator is 3
The denominator is 21
Reduce our fraction
Reduce the numerator by GCF
(1/3) x 3 = 1
Reduce the denominator by GCF
(1/3) x 21 = 7
Build our reduced answer

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 3/21, let's evaluate:
Whole Number = 3 / 21 = 0.14285714285714
Whole Number = Integer(0.14285714285714)
Whole Number = 0
Find the fractional portion of the mixed number
| (Numerator - Denominator x Whole Number) | |
| Denominator |
Using the values we entered and calculated, we get:
| Fraction Portion = | (3 - 21 x 0) |
| 21 |
| Fraction Portion = | 3 - 0 |
| 21 |
| Fraction Portion = | 3 |
| 21 |
Combine both pieces for the mixed number:
Mixed Number = Whole Number & fraction Portion
Mixed Number = 0 & 3/21
Write this as a whole number
Whole Number = 0
Final Answer

What 8 formulas are used for the Fractions and Mixed Numbers Calculator?
a/c + b/c = (a + b)/c
a/c - b/c = (a - b)/c
a/c * b/c = ab/c * c
a/b/c/d = ad/bc
Reciprocal of a/b = b/a
a/c - b/c = (a - b)/c
a/c * b/c = ab/c * c
a/b/c/d = ad/bc
Reciprocal of a/b = b/a
