Answer 1

А) 3/4:1/2=(3*2)/4*1)=3/2=1 цел 1/2=1,5
Б) 4/7:4/5=(4*5)/(4*7)=5/7
В) 18/19:9/1=(18*1)/(9*19)=2/19
Г) 11/1:22/31=(11*31)/22=31/2=15 цел 1/2=15,5
Д) 11 цел 2/5:3 цел 4/5=57/5:19/5=(57*5)/(5*19)=57/19=3
Е) 1 цел 9/11:2 цел 4/33= 20/11:70/33=(20*33)/(11*70)=6/7

Answer 2

а) 3/4 : 1/2 = (3/4) * (2/1) = 6/4 = 3/2

б) 4/7 : 4/5 = (4/7) * (5/4) = 20/28 = 5/7

в) 18/19 : 9 = (18/19) * (1/9) = 2/19

г) 11 : 22/31 = 11 * (31/22) = 341/22

д) 11 целых 2/5 : 3 целых 4/5 = (11 * 5 + 2) : (3 * 5 + 4) = 57/19

е) 1 целая 9/11 : 2 целых 4/33 = (1 * 33 + 9) : (2 * 33 + 4) = 42/70 = 6/10 = 3/5
