Question

1 7/9:2 2/3=?????? 3 3/5: 2 1/10=???? 3 3/8:1/8-1 5/14*7 РеШыТе ПоЖаЛуСтА

Answer 1

1) 1 ( 7/9 ) : 2 ( 2/3 ) = ( 16/9 ) * ( 3/8 ) = 2/3
2) 3 ( 3/5 ) : 2 ( 1/10 ) = ( 18/5 ) * ( 10/21 ) = 36/21 = 1 ( 15/21 )
3) 3 ( 3/8 ) : ( 1/8 ) - 1 ( 5/14 ) * 7 = ( 27/8 ) * 8 - ( 19/14 ) * 7 = 27 - ( 19/2 ) = 27 - 9,5 = 17,5
