If a recipe calls for 2 1/2 cups of sugar and you want to make a half portion of it, calculate the exact amount of sugar needed.

Sure, I can help you with that calculation. To adjust a recipe to a smaller or larger size, you'll need to modify the measurements accordingly. In this case, you need to reduce the sugar by half.

First, break down the measurement of 2 1/2 cups into its component parts - this will make the math easier.

- 2 cups is the same as 500 ml.
- 1/2 = 0.5 (conversion of fraction to decimal).

So, 2 1/2 cups sugar is equal to 3 cups or 750 ml sugar.

Now, you want to make 1/2 the amount, which means you need 1/2 of 750 ml sugar or 375 ml sugar.

However, you've stated that you only want 1/2 cup of sugar, not 1/2 of 750 ml. So, you need to convert 1/2 cup to ml.

1 cup = 240 ml. So, 1/2 cup = 120 ml.

Therefore, 1/2 cup of sugar is equivalent to 120 ml, or 120/240 x 375 = 187.5 ml.

However, I should mention that measurements in recipes may not always be exact, so it's possible that the recipe amount is rounded, and rounding fluid ounces down to half in this case can yield between approximately 120 and 128 ml, depending on your preference and how full you pour. In the case of fraft, you might round down to 120 ml/0.5 cups from a fluid measurement. However, I would always recommend not adding or removing more than 0.5 percent of the given quantity.

To calculate the amount of sugar needed for a half portion, you'll need to divide the original amount by 2. In this case, the original amount is 2.5 cups of sugar.

Amount of sugar for half portion = Original amount / 2

First, let's convert the mixed fraction 2 1/2 into an improper fraction:

2 1/2 = (2 * 2) + 1 / 2 = 5 / 2

Now, we can perform the division:

Amount of sugar for half portion = 5/2 ÷ 2

To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction:

Amount of sugar for half portion = 5/2 * 1/2 = 5/4

So, the amount of sugar needed for a half portion is 1.25 cups (since 5/4 equals 1.25 as a decimal). You will need 1.25 cups of sugar to make a half portion of the recipe.
