Question

2 разделить на 2 целых 2/3 плюс 1 целая 4/5 умножить 3 целых 1/3 минус 2 целых 5/6

Answer 1

$2/2 \frac{2}{3}+1 \frac{4}{5}*3 \frac{1}{3} -2 \frac{5}{6}= \frac{9}{12}+6-2 \frac{10}{12} =3 \frac{11}{12}$

Answer 2

1) 2 : 2 ( 2/3 ) = 2 : ( 8/3 ) = 3/4 ; 2) 1 ( 4/5 ) * 3 ( 1/3 ) = ( 9/5 ) * ( 10/3 ) = 6 ; 3) ( 3/4 ) + 6 - 2 ( 5/6 ) = 6 ( 3/4 ) - 2 ( 5/6 ) = 6 ( 9/12 ) - 2 ( 10/12 ) = 5 ( 21/12 ) - 2 ( 10/12 ) = 3 ( 11/12 ) ; Ответ 3 ( 11/12 )
