Answer:
The cookie recipe can be made 7 1/2 times.
Explanation:
To solve this you need to change 11 1/4 and 1 1/2 into improper fractions so you can get 45/4 and 3/2. Now you have to flip 3/2 so its 2/3, and you can cross cancel so since the 3 in 2/3 can go into the 45 in 45/4 fifteen times, 45/4 becomes 15/4 and 2/3 becomes 2/1. You can multiply across now, so if you multiply 15 and 2, you get 30, and if you multiply 4 and 1 you get 4, so now you have 30/4. To change 30/4 into a mixed number, you have to divide 30 by 4. Since 4 can go into 30 seven times, your whole number is 7, and since 28 + 2 = 30, your numerator is 2, while the denominator is 4. Also, 2/4 can be simplified to 1/2, so your final result is 7 1/2.
I hope this helps you :D
