3 Teaspoon

Step-by-step explanation:

Each \dfrac{1}{4} sheet of cake requires 0.75 teaspoon of baking soda.

Therefore, 1 whole cake will require x teaspoon of baking soda.

Expressing it as a ratio

\frac{1}{4}:0.75=1:x\\\frac{1/4}{0.75}=\frac{1}{x}  \\\text{Cross Multiply}\\\frac{1}{4}*x=0.75\\x=0.75*4\\x=3

A whole cake will need 3 teaspoon of baking soda.

Since the expressions are not provided, it is hoped that you will be able to learn from the above. You can comment if you need further help.
