Answer 3

69M 688CM

To add 45 meters and 78 centimeters to 23 meters and 910 centimeters, you first add the meters together: 45m + 23m = 68m. Then you add the centimeters together: 78cm + 910cm = 988cm. Since 100 centimeters make 1 meter, you can convert the 988cm to meters by dividing by 100, which gives you 9.88m. Adding this to the 68m gives you a total of 69m 688cm.
