We want to add the following 2 fractions:
| 1 | |
| 2 |
| + |
| 5 |
| 8 |
Denominator 1 ≠ Denominator 2.We need matching denominators
Multiply fraction 1 numerator * fraction 2 denominator.
Multiply fraction 2 numerator by the fraction 1 denominator
We add those 2 results, and get our numerator.
Our denominator is the product of the denominators of both fractions.
| Fraction 1 + Fraction 2 = | Numerator 1 x Denominator 2 + Numerator 2 x Denominator 1 |
| Denominator 1 x Denominator 2 |
| Fraction 1 + Fraction 2 = | 1 x 8 + 5 x 2 |
| 2 x 8 |
| Fraction 1 + Fraction 2 = | 8 + 10 |
| 16 |
| Fraction 1 + Fraction 2 = | 18 |
| 16 |
Reduce our fraction
Reduce the numerator by GCF
(1/2) x 18 = 9
Reduce the denominator by GCF
(1/2) x 16 = 8
Build our reduced answer
Answer = 9/8
| Answer = | 9 |
| 8 |

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
What 10 concepts are covered in the Fractions and Mixed Numbers Calculator?
- addition
- math operation involving the sum of elements
- denominator
- The bottom portion of a fraction. For a/b, b is the denominator
- division
- separate a number into parts
- fraction
- how many parts of a certain size exist
a/b where a is the numerator and b is the denominator - mixed number
- a number consisting of an integer and a proper fraction.
- multiplication
- math operation involving the product of elements
- numerator
- the number above the line in a common fraction
- reciprocal
- a number which when multiplied by x yields the multiplicative identity, 1
- simplify
- reducing the expression/fraction/problem in a simpler form.
- subtraction
- math operation involving the difference of elements
