Answer 1

Ответ:

2/3

Пошаговое объяснение:

1) 0,2 - 7/15 = 2/10 - 7/15 = 6/30 - 14/30 = -8/30 = -4/15

2) -4/15 * (-5/8) = -1/3 * (-1/2) = 1/6

3) -5/12 - 0,75 = -5/12 - 75/100 = -5/12 - 3/4 = -5/12 - 9/12 = -14/12 = -7/6

4) -7/6 : 2. 1/3 = -7/6 : 7/3 = -7/6 * 3/7 = -3/6

5) 1/6 - (-3/6) = 1/6 + 3/6 = 4/6 = 2/3

Answer 2

Ответ:

(0.2-7/15)*(-5/8)-(5/12-0.75):2 1/3=2/3

1)0.2-7/15=2/10-7/15=6/30-14/30=-8/30=-4/15

2)-4/15*(-5/8)=20/120=1/6

3)-5/12-0.75=-5/12-3/4=-5/12-9/12=-14/12=-7/6

4)-7/6:2 1/3=-7/6:7/3=-7/6*3/7=-21/42=-1/2

5)1/6-(-1/2)=1/6+1/2=1/6+3/6=4/6=2/3
