Your brother is going through a growth spurt. In January, he is 54 inches tall. In April, he is 63 inches tall. How many inches does your brother grow each month?

I believe the answer is 21 inches

Step-by-step explanation:

Because you have to do 63 divided by 3 because its been 3 months and that equals 21 and you label would be inches

21 inches each month

3 inches

Step-by-step explanation:

The brother is growing 3 inches per month, because if their 54 inches tall in January and 63 inches tall in April you do 63-54 to see how much he grown in three months which is 9. Then you do 9/3 and 3 is from their is a 3 month gap between January and April and you get 3 inches. So the brother grew 3 inches per month through January and April.
