Question

Viết các số đo độ dài (theo mẫu) : 3 m 75 mm = 3 m + 75/1000 m = 3 75/1000 m

5 m 25 mm = ..............................................................................................................

7 m 40 cm = ...............................................................................................................

15 m 5 mm = ..............................................................................................................

làm đúng theo mẫu giúp mik nhé

Answer 1

\(5m25mm=5m+\dfrac{25}{1000}m=5\dfrac{25}{1000}m\)

\(7m40cm=7m+\dfrac{40}{100}m=7\dfrac{40}{100}m\)

\(15m5mm=15m+\dfrac{5}{1000}m=15\dfrac{5}{1000}m\)

Answer 2

5 m 25 mm = 5m + 25mm = 5m + 25/1000 m = 5 25/1000 m

7 m 40 cm = 7m + 40cm = 7m + 40/100 m = 7 40/100 m

15 m 5 mm = 15m + 5mm = 15m + 5/1000 m = 15 5/1000 m 

Answer 3

5m 25mm =5 m +25/1000 m = 5\(\dfrac{25}{1000}\)m

7m 40cm = 7m + 40/100 m = 7\(\dfrac{40}{100}\)m

15m 5mm = 15m + 5/1000 m = 15\(\dfrac{5}{1000}\)m
