Adding and subtracting fractions
To add or subtract fractions we have to start by getting the denominators to be identical. We then add the numerators together and finally simplify the fraction, if necessary.
we first notice that the denominators are both 5 - so we don't need to do anything in the first step. So, we just need to add the numerators together and simplify the fraction ...
Lets try another example, say we have the sum ...
First we have to get the two denominators to be the same. To do this we can ...
- multiply the numerator & denominator in the first fraction by 5
- and multiply the numerator & denominator in the second fraction by 4
This way, the denominator of both fractions will be equal to 20!
