Answer 3

Calculating the Sum of 3m 21cm and 4m 99cm

To calculate the sum of 3m 21cm and 4m 99cm, we can add the meters and centimeters separately.

First, let's add the meters: 3m + 4m = 7m

Next, let's add the centimeters: 21cm + 99cm = 120cm

Now, we need to convert the 120cm to meters and add it to the total meters.

Converting 120cm to meters: 1 meter = 100 centimeters, so 120cm is equal to 1m 20cm.

Adding the converted centimeters to the total meters: 7m + 1m = 8m 20cm

So, the sum of 3m 21cm and 4m 99cm is 8m 20cm.
