Question

А ) ( 1 3\8 + 1 3\4 - 0 ,411 ) : 0 , 59 =
б ) ( 6 7\15 - 1 , 4 ) : ( 2 4\5 + 1 , 2 ) =

Answer 1

А) (1 3/8 + 2 3/4 -0,411) : 0,59=6,3
11/8 +11/4=33/8 =4,125
4,125 - 0,411 =3,714
3,714 :0,59 =6,3

б) (6 7/15 - 1,4) : (2 4/5+1,2)= 1,27
(6 7/15 =6,47) (6,47 - 1,4) =5,07
( 2 4/5 =2,8) (2,8 + 1,2) = 4
5,07 : 4 = 1,27
