Adding Mixed Numbers.

This is my mini scribepost on adding mixed numbers.

These are the mixed numbers I will be adding.
1 3/4 + 1 1/8 =
2 4/5 + 1 1/2 =


1 3/4 + 1 1/8=1 12/16 + 1 2/16 = 2 7/8


I added the whole numbers first and which added up to 2. Then I made the denominator 16 instead of 32 because it would take longer. I knew 3 quarters of 16 was 12 and 1 eighth of 16 was 2. Then after, you just add the fractions and it would be 14. But since 14 and 16 were equal, i divided it by 2. So the fractions is 7 over 8. Made it into a simplified fraction.

2 4/5 + 1 1/2 = 4 3/10

I made the denominator 10 because 5x2=10. Then I made the numerator 8 because 5 fits into 10, 2 times. Then I made the other numerator 5 because 2 fits into 10, 5 times. I knew if you added 5+8 it would make an improper fraction. So I made another whole number. Then I added all the whole numbers up and it became 4 3/10.
