4 3/5 : ( 1 2/3 - 3 1/5 ) + 1 3/8= - 1 5/8
1) 1 2/3 - 3 1/5 = 1 10/15 - 3 3/15 = -1 8/15
2) 4 3/5 : (- 1 8/15) = - ( 23/5 * 15/23 ) = -3
3) -3 + 1 3/8 = - 1 5/8
Выражением:
4 3/5 : ( 1 2/3 - 3 1/5 ) + 1 3/8=
= 23/5 : ( 5/3 - 16/5 ) + 11/8 =
= 23/5 : ( (25-48) /15) + 11/8=
= 23/5 * (-15/23) + 11/8=
= - 3/1 + 11/8 = - 24/8 + 11/8 =
= - 13/8 = - 1 5/8
