Given the tape diagram and the information about the ratio of sugar to cinnamon, we can interpret and complete the table step by step.

The tape diagram shows:

• Sugar has 3 equal parts.
• Cinnamon has 2 equal parts. This gives a ratio of sugar to cinnamon of $3:2$.

Now, we are told that $12\, \text{g}$ of cinnamon corresponds to the 2 parts of cinnamon. Therefore, each part in the diagram represents:

$\frac{12\, \text{g}}{2} = 6\, \text{g} \text{ per part}.$

Since sugar has 3 parts, the total amount of sugar will be:

$3 \times 6 = 18\, \text{g}.$

Completing the table:

Original ratio	Amount (g)
Sugar	18
Cinnamon	12
Total topping	$18 + 12 = 30$

The total topping is the sum of sugar and cinnamon, which is 30 grams.
