Question

(1/4-2/3)*(4/5-2/15)*(-3/5)

(3/8-1/6)*(2/9-2/5)*27​

Answer 1

Пошаговое объяснение:

(1/4-2/3)*(4/5-2/15)*(-3/5)=1/6

1/4-2/3=(3-8)/12=-5/12

4/5-2/15=(12-2)/15=10/15=2/3

2/3*(-3/5)=-2/5

-5/12*(-2/5)=1/6

(3/8-1/6)*(2/9-2/5)*27=-1

3/8-1/6=(9-4)/24=5/24

2/9-2/5=(10-18)/45=-8/45

5/24*(-8/45)=-1/27

-1/27*27=-1
