Answer 1

a)1/2 • 17/5 = 17/10 = 1,7

b)-27/8 • 4/108 = -1/8

c)(-8 + 14/3 - 31/6) • 18/17 =

(-51/6) • 18/17 = (-9)

d)100/3 • (-27/5) = (-180)

Answer 2

a)

| -2/5 - 1/10 | · | -3,4 | =

= | (- 4 - 1)/10 | · 34/10

= | - 5/10 | · 17/5

= 5/10 · 17/5

= 17/10

= 1,7

b)

- 27/| - 8 | ·(2²)/(5³ - 17) =

= -27/8 · 4/(125 - 17)

= - 27/8⁽⁴ · 4/108⁽²⁷

= - 1/2 · 1/4

= -1/8

c)

(- 8 + 4 2/3 - 5 1/6) · | - 18/17 | =

= (- 8 + 14/3 - 31/6) · 18/17

= (- 48 + 28 - 31)/6 · 18/17

= - 51⁽¹⁷/6 · 18⁽⁶/17

= - 9

d)

| 900⁽⁹/ - 27⁽⁹ | · (1,36 - 6,76) =

= 100/3 · (136/100 - 676/100)

= 100/3 · (- 540/100)

= - 540/3

= - 180
