25.8 -12.5+170:17-8
\(a\)\(=6+182+3.3\)
\(=188+9=197\)
\(b;15-200:50\)
\(=15-4=11\)
\(c;200-60+\frac{170}{7}-8\)
\(=140+\frac{114}{7}\)
\(=\frac{1094}{7}\)
a)18 : 3 + 182 + 3.(51:17)
= 6 + 182 + 3.3
= 188 + 9
= 197
b) 15 - 25.8:(100:2)
= 15 - 200 : 50
= 15 - 4
= 11
c) 25.8 - 12.5 + 170:17 - 8
= 200 - 60 + 10 - 8
= 142
B = 2 5 . 8 + 2 8 . 11 + 2 11 . 14 + . . . + 2 92 . 95

Nhớ nhé!
15 - 25 . 8 . ( 100 . 2 )
= 15 - 25 . 8 . 200
= 15 - 1000 . 200
= 15 - 200000
= - 199985

Helppppppp meeeeeee

đây bn
