Today in Skills, Mr Harbeck told us to answer these two questions:

1 3/4 + 1 1/8 =

2 4/5 + 1 1/2 =

And we were told to explain how to add the mixed numbers.

Here is the first question:

1 3/4 + 1 1/8=

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

So what I did was that I added the whole numbers first and it was 2. Then I made the denominator 16 instead of 32 because it would save me some time. I knew 3 quarters of 16 were 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.

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

So what I was was that 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.

That is how you add mixed fractions. Thank you.
