3. 1 1/5+2 2/5
4. 3-1/3
5. 5 3/4-3 1/8
Please give me a solution to how can I solve it

 

Answer:

1. 3/4

2. 2 13/15

3. 3 3/5

4. 2 2/3

5. 2 5/8

Step-by-step explanation:

1. add the numerator and copy the denominator

2. tranfer into improper, and get the lcd

11/5 + 2/3 = 33+10/15

=43/15 or 2 13/15

3. add the whole number and the numerator and copy the denominator

4. get the lcd

3/1-1/3 = 9-1/3

=8/3 or 2 2/3

5. tranfer into improper, and get the lcd

23/4-25/8 = 46-25/8

=21/8 or 2 5/8
