Mr. Patel used 4.5 bags of seed
Solution:
Given that,
Over the summer, Mr. Patel refilled a bird feeder 24 times using 6 cups of seed each time
A bag of seeds holds 32 cups
1 bag of seed = 32 cups
Given that Patel refilled 24 times using 6 cups of seed each time
Then, the number of cups used for the 24 times is given as:

Now we have to find the bags of seed needed for 144 cups
Let "x" be the number of bags of seed for 144 cups
From given,
1 bag of seed = 32 cups
"x" bags of seed = 144 cups
This forms a proportion and we can solve it by cross multiplying

Thus 4.5 bags of seed is used by Mr.patel
