Question

Выполните действия:(-2/3 +4,32)-(6,82-1/6)

Answer 1

-2/3+4.32-6.82+1/6=1/6-4/6-2.5= -3/6-2,5=-0,5-2,5= -3

Answer 2

а откуда взялось 100?

Answer 3

4.32=432/100

Answer 4

( - 2/3 + 4,32) - ( 6,82 - 1/6) = - 3
1) 4,32 - 2/3 = 432/100 - 2/3 = 108/25 - 2/3 = (324 - 50) / 75 = 274/75
2) 6,82 - 1/6 = 682/100 - 1/6 = 341/50 - 1/6 = (1023 - 25)/ 150 = 998/150 = =499/75
3) 274/75 - 499/75 = ( 274 - 499) / 75 = - 225 / 75 = - 3

Ответ: - 3
