Answer:
168
Step-by-step explanation:
Yubin can make 168 cookies.
15 3/4 as a decimal is 15.75. 2 1/4 as a decimal is 2.25. 15.75 divided by 2.25 is 7. You would then do 7 times 24 because that's how many cookies 2.25 cups of flour makes, and you get 168. Your answer is 168 cookies.

To make it simple, just subtract the age that you died to the age that you were born.
1730 - 1620 = 110
Which means that you would die at the age of 110 if you were born at 1620 and died on 1730.
