how many cups of water will I need to make a smaller portion of dough 1/6 using 2/5 cups of water.

To calculate how many cups of water you will need to make a smaller portion of dough, given that the original recipe calls for 2/5 cups of water, you first need to determine the proportion of the recipe you are making.

In this case, the smaller portion you want to make is 1/6 of the original recipe. To find out how much water you will need for this smaller portion, follow these steps:

1. Calculate the proportion of the recipe you are making:
smaller portion = 1/6

2. Multiply the proportion by the original amount of water:
smaller portion * original water amount = 1/6 * 2/5 (since 2/5 cups is the original water amount)

To simplify the calculation, let's convert the fractions to decimals:

1/6 * 2/5 = (1/6) * (2/5) = 2/30 = 1/15

3. Now, you have calculated that you will need 1/15 cups of water for the smaller portion of dough.

To convert the fraction to a decimal, divide the numerator (1) by the denominator (15):

1/15 = 0.0667 cups of water (rounded to four decimal places)

Therefore, you will need approximately 0.0667 cups of water, or about 1/15 cups of water, for the smaller portion of dough.
