Adding fractions with a different denominator

L.I to add fractions that have different denominators. This week for Maths we learnt how to add fractions that have different denominators. I made a slide presentation on how to add fractions. I used the fractions 3/5 + 4/5. I found out, after a lot of hard thinking that my answer cam up to 50/60. Which is 50 over 60. We had to use multiplication and addition in the explanation.
