Answer:

2. 4655/150

3. 81/12

4. 19/6

5. -76/21

Step-by-step explanation:

2. 15*10=150

36*15+2=542

5*10+1=51

542*10=5420/150

51*15=756/150

5420/150-756/150=4655/150

3.3*4=12

6*3+3/=21*4=84/12

1*3=3/12

84/12-3/12=81/12

4. 3*2=6

3*3+2=11

11*2=22/6

1*3=3/6

22/6-3/6=19/6

5. 7*3=21

4*3+1=13

5*3=15/21

13*7=91/21

15/21-91/21=-76/21
