2) 5/6 + 1/6 = 6/6 = 1

2. 1) 6/5 - 3/4 = 24/20 - 15/20 = 9/20
2)9/20*2/3= 3/10

3. 1) 6/5-2/3=18/15-10/15=8/15
2) 8/15*1/2=4/15

4. 1) 4/9*3/16=1/3*1/4=1/12
2) 11/18-1/12=22/36-3/36=19/36

5. 1) 5/18*6/25=1/3*1/5=1/15
2) 29/30-1/15=29/30-2/30=27/30=9/10

6. 1) 3/4+11/8=6/8+11/8=17/8
2) 8/5*17/8=1/5*17/1=17/5=3 2/5
