Answer:
6 teaspoons of baking powder required.
Explanation:
Given that
According to the recipe of pancake,
For every teaspoon of salt, 2 teaspoons of baking baking powder is required.
To find:
How much baking powder will be needed, if 1 teaspoon of salt was used ?
Solution:
This problem can be solved using ratio.
teaspoon of salt : 2 teaspoons of baking powder
Let us multiply the above ratio with 3.
teaspoon of salt : 2
3 teaspoons of baking powder
OR
1 teaspoon of salt : 6 teaspoons of baking powder
So, answer is <em>6 teaspoons </em>of baking powder required.
Also, we can use the unitary method:
teaspoon of salt needs = 2 teaspoons of baking powder
1 teaspoon of salt needs = teaspoons of baking powder
1 teaspoon of salt needs = 2 3 = <em>6</em> teaspoons of baking powder needed
So, the answer is:
<em>6 teaspoons of baking powder </em>required.
