Today I learnt...

How to add 2 different fractions for e.g 3/4 + 2/5. You first have to times the denominators from the fractions e.g 4 x 5 = 20. There are 2 ways to do 20 with 4 and 5. 4 x 5 and 5 x 4. You need to times the 3 from 3/4 and times it by 5 which makes it 15. put the 15 and 20 together and you get 15/20. Then you times the 2 with 4 which gives you 8. Put it with 20 and you get 8/20. Add those 2 fractions together and you get 23/20. You can simplify that by 1 3/20.
