Final answer:
The difference between 47 m 20 cm and 19 m 60 cm is 28 m 60 cm.
Step-by-step explanation:
To find the difference between 47 m 20 cm and 19 m 60 cm, we subtract the centimeters first. In the ones place, we have 20 - 60, which is -40. Since we cannot have a negative number in the ones place, we borrow 1 from the tens place. This gives us 120 - 60 = 60. Next, we subtract the meters, which gives us 47 - 19 = 28. So, the difference between 47 m 20 cm and 19 m 60 cm is 28 m 60 cm.
