To convert cups to teaspoons, you can use the fact that there are 48 teaspoons in 1 cup.
Given that you have 1,200 tablespoons in 5 cups, you need to first convert tablespoons to teaspoons. Since there are 3 teaspoons in 1 tablespoon, you can convert by multiplying:
1,200 tablespoons × 3 teaspoons/tablespoon = 3,600 teaspoons.
Now, to find the number of teaspoons in 1 cup, you divide the total teaspoons by the number of cups:
3,600 teaspoons ÷ 5 cups = 720 teaspoons per cup.
In terms of your options, the correct method to find how many teaspoons are in 1 cup based on the information given is:
Divide 1,200 by 5 (to find the number of tablespoons per cup), then multiply by 3 to convert to teaspoons, or directly convert using the known ratio.
However, it seems like no option represents that straightforward calculation. The focus should be on converting the total accurately.
So, the best step from your listed options would be:
Divide 1,200 by 5.
This step finds the number of tablespoons in 1 cup, which you can later multiply by 3 to find teaspoons if you wanted.
