Answer :

To determine how many teaspoons are in 6 tablespoons, we start by knowing that there are a fixed number of teaspoons in each tablespoon.

1. First, we recognize that one tablespoon is equivalent to 3 teaspoons.
2. Next, we need to find out how many teaspoons are in a total of 6 tablespoons.
3. To do this, we multiply the number of tablespoons by the number of teaspoons per tablespoon:
- Number of tablespoons = 6
- Number of teaspoons per tablespoon = 3
4. Calculate:
[tex]\[ 6 \, \text{tablespoons} \times 3 \, \text{teaspoons per tablespoon} = 18 \, \text{teaspoons} \][/tex]

Therefore, the number of teaspoons in 6 tablespoons is 18.

The correct answer is:
O b. 18
