-4 * 3 4/15= - (4 * 3+4*4/15)= - (12+16/15)= - (12+1 1/15)= - 13 1/15

3 3/7 :(- 16)= - 24/7 * 1/16= - 3/7*2= - 3/14

- 6 1/12+2 5/6= - 6 1/12 + 2 10/12= - (5 13/12 - 2 10/12)= - 3 3/12= - 3 1/4

-4 5/11 - 3 7/11= - (4 5/11+3 7/11)= - 7 12/11= - 8 1/11

2 4/5 * (-3/16)= - 14/5 * 3/16= - 21/40

-3 1/8 : (-2 2/9)=3 1/8 : 2 2/9=25/8 * 9/20=45/32=1 13/32

-2 3/4 * (-1)=2 3/4
