112;

15⅔;

178;

1910;

1811

Answer 1

145 = 1*54 = 54 = 1 14

112= 1*21 = 2

15⅔ = 1/173 = 1*317 = 317

178 = 1*87 = 87 = 1 17

1910 = 1*109 = 109 = 1 19

1811 = 1*118 = 118 = 1 38

Answer 2

1) можно решить так: 1:4/5 то=>
145 = 1*54 = 54 = 1 14

112= 1*21 = 2

15⅔ = 1/173 = 1*317 = 317

178 = 1*87 = 87 = 1 17

1910 = 1*109 = 109 = 1 19

1811 = 1*118 = 118 = 1 38
если 1/4:5 то=>
2)
145=1/4*1/5=1/20

112=1/2=0,5

15⅔=1/5*3/2=3/10=0,3

178=1/7*1/8=1/56

1910=1/9*1/10=1/90

1811=1/8*1/11=1/88
