Let’s solve each problem one by one, step by step.

Problem 1:
A baker has 18 pounds of dough.
Each croissant uses ¼ pound of dough.
We want to know how many croissants he can make.
Think: If each croissant takes ¼ pound, then in 1 pound, you can make 4 croissants (because 4 × ¼ = 1).
So in 18 pounds, you can make:
18 × 4 = 72 croissants.
✔ Check: 72 croissants × ¼ pound each = 72 ÷ 4 = 18 pounds. Correct!

Problem 2:
The assistant is putting ⅓ cup of cream on top of each bowl of soup.
There are 12 cups of cream total.
We want to know how many bowls she can prepare.
Think: Each bowl uses ⅓ cup. So how many ⅓ cups are in 12 cups?
That means: 12 ÷ (⅓) = 12 × 3 = 36 bowls.
✔ Check: 36 bowls × ⅓ cup = 36 ÷ 3 = 12 cups. Correct!
(Note: The 3 pots of soup is extra info — we don’t need it because we’re told there are 12 cups of cream total.)

Problem 3:
Each box has 16 servings.
Each serving has 4 cookies.
Total weight of the box is ½ kilogram.
We want the weight of
each cookie.
First, find total number of cookies in the box:
16 servings × 4 cookies per serving = 64 cookies.
Total weight = ½ kg.
So, weight per cookie = ½ ÷ 64.
Dividing by 64 is the same as multiplying by 1/64:
½ × 1/64 = 1/(2×64) = 1/128 kg per cookie.
✔ Check: 64 cookies × 1/128 kg = 64/128 = ½ kg. Correct!

Final Answer:
1. 72 croissants
2. 36 bowls
3. 1/128 kilogram
