Viết số thập phân thích hợp vào chỗ chấm (theo mẫu):
7 d m = 7 10 m = 0 , 7 m 9 d m = 9 10 m = ⋯ m 5 c m = 5 100 m = ⋯ m 8 c m = 8 100 m = ⋯ m
7 d m = 7 10 m = 0 , 7 m 9 d m = 9 10 m = 0 , 9 m 5 c m = 5 100 m = 0 , 05 m 8 c m = 8 100 m = 0 , 08 m
Tính giá trị biểu thức a) 50 + 50 : m + 100 với m = 5 b) ( m + n + p) × 2 với m = 62cm ; n = 7dm ; p = 81cm
a: Khi m=5 thì 50+50:m+100=50+50:5+100=150+10=160
b: n=7dm=70cm
\(\left(m+n+p\right)\cdot2=\left(62+70+81\right)\cdot2=426\left(cm\right)\)
