Answer 1

\(272:16-5+4\left(30-6-255:17\right)\)

\(=17-5+4.9\)

\(=12+36\)

\(=48\)

\(25.8-12.5+272:17-8\)

\(=200-60+16-8\)

\(=140+16-8\)

\(=148\)

Answer 2

272 : 16 - 5 + 4(30 - 6 - 255 : 17)

          = 17 - 5 + 4.9

          = 12 + 36

          = 48

      2. 25 . 8 - 12.5 + 272 : 17 - 8

        = 200 - 60 + 16 - 8

        = 140 + 16 - 8

        = 148

Answer 3

dễ mà bạn

272:16-5+4(30-6-255:17)

= 272:16-5+4(30-6-15)

= 272:16-5+4(24-15)

= 272:16-5+4.9

= 17-5+36

= 12+36=48

25.8-12.5+272:17-8

= 200-60+16-8

= 140+16-8

= 156-8

= 148
