Answer 1

Ответ:

1) -2¼

Пошаговое объяснение:

Х-9/2=-9/4

Х=-9/4+9/2

Х=9/2-9/4=(18-9)/4=9/4=2¼

2) -3 ³/¹⁰

-х= 6⅘-3½

-х= ³⁴/5-⁷/²

-х= (34*2-7*5)/10

-х= 33/10

х= - 3 ³/10

3) -6 ⅝

-х= 11½-4⅞

-х=23/2 - 39/8

-х= (23*4-39)/8

-х= 53/8

х= - 6⅝

Answer 2

1) -4 + 1/2 = -8/2 + 1/2 = -7/2 = -3.5 2) -6 + 4/5 = -30/5 + 4/5 = -26/5 = -5.2 3) -11 + 1/2 = -22/2 + 1/2 = -21/2 = -10.5

Поэтому: 1) -4 + 1/2 = -3.5 2) -6 + 4/5 = -5.2 3) -11 + 1/2 = -10.5
