Question

Найдите значение выражения ( 1 3/8 + 3/4 - 0,355 ) :0,59

Answer 1

1 3/8 = 1,375
3/4 = 0,75
(1,375+0,75-0,355):0,59 = (2,125-0,355):0,59 = 1,77:0,59 = 3

Answer 2

1) 1 3/8 + 3/4 = 1 3/8 + 6/8 = 2 1/8

2) 2 1/8 -  0,355 = 17/8 - 355/1000 =17/8 - 71/200 = 25*17/8 - 71/200 = 425/200 - 71/200=354/200 = 177/100

3) 177/100 : 59/100 = 177/100 *100/59 = 177/59 = 3
