Today for Maths, my maths group & I learnt about adding & subtracting fractions with related denominators. The first step is we needed to figure out the multiples of the 2 denominators, also knwon as LCD (Least Common Denominator). Next we had to modify a fraction so that both denominators are the same. Once the denominators are the same, you can now add & subtract them but the denominators stay the same.
