Answer 1

`b)1728:(2,92+6,68)-45,16`

`=1728:9,6-45,16`

`=180-45,16`

`=134,84`

`d) ( 128,4 - 73,20 ) : 240 + 18,32`

`= 55,2 : 240 + 18,32`

`= 0,23 + 18,32`

`= 18,55.`

Answer 2

b)

= 1728 : 9.6 - 45.16

= 180 - 45.16

= 134.84

d)

= 55.2 : 240 + 18.32

= 23 - 18,32

= 18.55

Answer 3

b) \(1728:\left(2,92+6,68\right)-45,16\)

\(=1728:9,6-45,16\)

\(=180-45,16\)

\(=134,84\)

d) \(\left(128,4-73,20\right):240+18,32\)

\(=55,2:240+18,32\)

\(=0.23+18,32\)

\(=18,55\)
