.

5

centimeters tall, and Chang massed

4

.

54

kilograms and was

51

centimeters tall.

\newline

How much did the babies mass in total?

\newline

kilograms

Calculate Total Mass: To find the total mass of the babies, we need to add the mass of Adrian to the mass of Chang. $\newline$ Adrian's mass = $2.87$ kilograms $\newline$ Chang's mass = $4.54$ kilograms $\newline$ Total mass = Adrian's mass + Chang's mass $\newline$ Total mass = $2.87 \, \text{kg} + 4.54 \, \text{kg}$
Perform Addition: Now we perform the addition to find the total mass. $2.87\,\text{kg} + 4.54\,\text{kg} = 7.41\,\text{kg}$
