1. 2 4/5+3= 2. 3 3/7+5 2/4= 3. 3 2/3-2 1/4= 4. 5/6+3/4= 5. 7/12-5/4= tolong dengan caranya ya!

1. 2 4/5+3= 14/5 + 3
= 14/5 + 15/5
= 29/5
= 5 4/5

2. 3 3/7+5 2/4= 24/7 + 22/4
= 96/28 + 154/28
= 250/28
= 8 26/28
= 8 13/14

3. 3 2/3-2 1/4= 11/3 - 9/4
= 44/12 - 27/12
= 17/12
= 1 5/12

4. 5/6+3/4= 10/12 + 9/12
= 19/12

5. 7/12-5/4=7/12 - 15/12
= - 8/12
= - 2/3

Semoga membantu jawaban dari saya
