viet cac so do do dai [theo mau]

mau; 2m5 dm =2m=2m+5/10m=2 5/10m

7m8dm=

5cm 3mm=

1m 12 cm

8m 9 cm=

Answer 1

[Chu Quyen Nhan]

7 m 8 dm = 7 m + 8/10 m = 7 8/10 m

5 cm 3 mm = 5 cm + 3/10 cm = 5 3/10 cm 

1 m 12 cm = 1 m + 12/100 m = 1 12/100 m 

8m 9 cm = 8 m + 9/100 m = 8 9/100 m 

Answer 2

[Nguyễn Tiến Dũng]

\(7m8dm=7m+\frac{8}{10}m=7m+\frac{4}{5}m=7\frac{4}{5}m\)

\(5cm3mm=5cm+\frac{3}{10}cm=5\frac{3}{10}cm\)

\(1m12cm=1m+\frac{12}{100}m=1m+\frac{3}{25}m=1\frac{3}{25}m\)

\(8m9cm=8m+\frac{9}{100}m=8\frac{9}{100}m\)
