Спасибо огромное :)))

1. (16/9)*((15/32)/(55/36))=(16*15*36)/(9*32*55)=6/11. 2. (25/7)/(8/7)*(2/3)=(25*7*2)/(7*8*3)=50/24=2+1/12. 3. (25/7)/((8/7)*(2/3))=(25*21)/(7*16)=75/16=4,6875. 4. (5/12+1/8)/(3/8)=((10+3)/24)/(3/8)=(13*8)/(24*3)=13/9=1+4/9. 5. 5/12+1/3=9/12=0,75. 6. (20/7)/((5/6)-(9/14))=(20/7)/((35-27)/42)=(20*42)/(7*8)=15. 7. (20/7)/(5/6)-9/14=24/7-9/14=39/14=2+11/14. 8. (9/4)/(15/11)-3/7=33/20-3/7=(231-60)/140=171/140=1+31/140.
