gary is 61 1/8" tall. His friends gino and gilbert are 56 1/2" tall and 63 1/8" tall. what is the average height of the three friends.

Do i divide my answer by 3?

Yes. Add the heights together and divide the sum by 3.

Yes, to find the average height of the three friends (Gary, Gino, and Gilbert), you need to add up their heights and then divide the sum by 3. Let's calculate it step by step.

1. Convert all the heights to a common denominator for easier calculation. In this case, let's use 8 as the common denominator.
- Gary's height is 61 1/8", which can be written as 61 + 1/8 = 61 + 1/8 = 61 + 1/8 = 61 + 2/16 = 61 2/16".
- Gino's height is 56 1/2", which can be written as 56 + 1/2 = 56 + 4/8 = 56 4/8".
- Gilbert's height is 63 1/8", which can be written as 63 + 1/8 = 63 + 1/8 = 63 + 2/16 = 63 2/16".

2. Add up the heights:
- Gary's height = 61 2/16"
- Gino's height = 56 4/8"
- Gilbert's height = 63 2/16"

Add the numerators: 2 + 4 + 2 = 8.
The sum of the heights is 61 2/16" + 56 4/8" + 63 2/16" = 180 8/16".

3. Simplify the sum, if possible:
180 8/16" can be simplified to 180 + 8/16 = 180 + 1/2 = 180 1/2".

4. Finally, divide the sum by 3 to find the average height:
Average height = (180 1/2") / 3 = 180 1/2" รท 3 = 60 1/2" per person.

Therefore, the average height of the three friends is 60 1/2" per person.
