a, c, e = numerator

b, d, f = denominator

-- = fraction line

Fraction is numerical quantity that is not a whole number.

• the top number (the numerator) says how many parts we have.

• the bottom number (the denominator) says how many parts the whole is divided into

• the top number (the numerator) says how many parts we have.

• the bottom number (the denominator) says how many parts the whole is divided into

numeratorA is 1

denominatorA is 2

numeratorB is 2

denominatorB is 5

1 | 2 | 1 | ||

---- | - |
---- | = |
----- |

2 | 5 | 10 |

When subtracting fractions, we first need to find the least common denominator of denominators A and B, which in our case is 10 (10 is divisible by both 2 and 5).

**numeratorA** is then multiplied by the number of times denominatorA (2) fits into the common denominator (10).

10/2 = 5

numeratorA is then 1 * 5 = 5

We do the same for **numeratorB**

10/5 = 2

numeratorB is then

2 * 2 = 4

The common numerator is then 5 - 4 = 1
