Joseph adopted puppy.the puppy gained 6whole 3/4 pounds 1st month,8whole 1/3 in 2nd month,10whole 5/6 in 3rd month,7whole 7/8 in 4th month.what was the puppy's average weight per month?

To find the average weight per month, we first need to find the total weight gained by the puppy over the 4 months.

Total weight gained = 6 3/4 + 8 1/3 + 10 5/6 + 7 7/8
Total weight gained = 27/4 + 25/3 + 65/6 + 63/8
Total weight gained = 135/12 + 100/12 + 130/12 + 94/12
Total weight gained = 459/12
Total weight gained = 38 3/4 pounds

Now, to find the average weight per month, we divide the total weight gained by the number of months.

Average weight per month = Total weight gained / Number of months
Average weight per month = 38 3/4 / 4
Average weight per month = 9 5/8 pounds

Therefore, the puppy's average weight per month was 9 5/8 pounds.

Step 1: Convert all mixed numbers to fractions

6 whole 3/4 = 27/4 pounds
8 whole 1/3 = 25/3 pounds
10 whole 5/6 = 65/6 pounds
7 whole 7/8 = 63/8 pounds

Step 2: Add up the weight gained in each month

27/4 + 25/3 + 65/6 + 63/8 = 2311/24 pounds

Step 3: Divide the total weight gained by the number of months

2311/24 ÷ 4 = 577.75/24 pounds

Step 4: Convert the fraction to a decimal

577.75/24 = 24.07 pounds

Therefore, the puppy's average weight gain per month was 24.07 pounds.
