Explanation:

First Problem (Baker Decorating Cakes)

Step1: Identify the operation.

We need to find the total time for 4 cakes, so we multiply the time per cake by the number of cakes. Let's assume the time per cake is $\frac{3}{4}$ hour (since it's likely a fraction, maybe a typo as % hour doesn't make sense, probably $\frac{3}{4}$).

Step2: Perform the multiplication.

Total time = Time per cake × Number of cakes = $\frac{3}{4} \times 4$

Step3: Calculate the result.

$\frac{3}{4} \times 4 = 3$ hours.

Step1: Identify the operation.

To find the total cost for 15 days, we multiply the cost per day by the number of days.

Step2: Perform the multiplication.

Total cost = Cost per cup × Number of days = $3.45 \times 15$

Step3: Calculate the result.

$3.45 \times 15 = 51.75$ dollars.

Step1: Identify the operation.

To find the amount per bottle, we divide the total honey by the number of bottles.

Step2: Perform the division.

Honey per bottle = Total honey ÷ Number of bottles = $22.5 \div 9$

Step3: Calculate the result.

$22.5 \div 9 = 2.5$ fluid ounces.

Answer:

The baker needs 3 hours. The operation is multiplication because we find the total by repeating the time for each cake 4 times.
