If i have three 1/4th teaspoon of salt, what does that equal to in grams?

3(1/4) teaspoon--- > (3*4+1)/4=13/4 teaspoon

1 teaspoon of salt > 5.69 gr
13/4 X

X=(13/4)*5.69=18.49 gr

the answer is 18.49 gr

18.49 g

Explanation:

1) First you need to know how many grams of salt are in a full teaspon.

Doing research you can find 1 teaspoon of salt = 5.69 grams

2) Second, set such ratio:

1 teaspon

5.69 grams

3) Third, convert three 1/4th teaspoon to numbers:

3 + 1/4 = (3*4 + 1) / 4 = (12 + 1) / 4 = 13 / 4

4) Fourth, set a ratio with 13/4 teaspoon the unknown amount of salt in grams:

13/4 teaspoon

           x

5) Fifth, set a proportion with the two ratios:

1 teaspoon         13/4 teaspoon
= 
   5.69 g                       x

6) Finally, solve for x

x = 13/4 teaspoon * 5.69 g / 1 teaspoon

x = 18.49 g.
