Question

Многоэтажные дроби пж вычислите 1\4\5; 1\1\2; 1\5⅔; 1\7\8; 1\9\10; 1\8\11

Answer 1

1\4\5 = 1*5\4 = 5\4 = 1 1\4

1\1\2= 1*2\1 = 2

1\5⅔ = 1/17\3 = 1*3\17 = 3\17

1\7\8 = 1*8\7 = 8\7 = 1 1\7

1\9\10 = 1*10\9 = 10\9 = 1 1\9

1\8\11 = 1*11\8 = 11\8 = 1 3\8

Answer 2

1) можно решить так: 1:4/5 то=>
1\4\5 = 1*5\4 = 5\4 = 1 1\4

1\1\2= 1*2\1 = 2

1\5⅔ = 1/17\3 = 1*3\17 = 3\17

1\7\8 = 1*8\7 = 8\7 = 1 1\7

1\9\10 = 1*10\9 = 10\9 = 1 1\9

1\8\11 = 1*11\8 = 11\8 = 1 3\8
если 1/4:5 то=>
2)
1\4\5=1/4*1/5=1/20

1\1\2=1/2=0,5

1\5⅔=1/5*3/2=3/10=0,3

1\7\8=1/7*1/8=1/56

1\9\10=1/9*1/10=1/90

1\8\11=1/8*1/11=1/88
