When reducing a recipe by half that originally calls for 3 lb. 8 oz. of sugar, what amount is needed?

• A. 1 lb 4 oz
• B. 1 lb 12 oz
• C. 2 lb
• D. 1 lb

Answer: (B)

To determine the correct amount of sugar needed when reducing a recipe from 3 lb. 8 oz. by half, start by converting the weight into a single unit for easier calculations. The original weight is 3 lb. 8 oz. First, convert the pounds to ounces: - 1 pound = 16 ounces, so 3 pounds = 3 x 16 = 48 ounces. - Therefore, 3 lb. 8 oz. = 48 oz. + 8 oz. = 56 oz. Now, to find the amount needed when the recipe is halved: - Divide the total ounces by 2: 56 oz. ÷ 2 = 28 oz. Next, convert 28 ounces back into pounds and ounces: - Since there are 16 ounces in a pound, divide 28 by 16. There is 1 pound in 16 ounces, which gives you 1 lb. with a remainder. - 28 oz. - 16 oz. (1 lb.) = 12 oz. Thus, when halved, the amount of sugar needed is 1 lb. 12 oz. This aligns with the answer option that states 1 lb. 12 oz.

To determine the correct amount of sugar needed when reducing a recipe from 3 lb. 8 oz. by half, start by converting the weight into a single unit for easier calculations.

The original weight is 3 lb. 8 oz.

First, convert the pounds to ounces:

• 1 pound = 16 ounces, so 3 pounds = 3 x 16 = 48 ounces.

• Therefore, 3 lb. 8 oz. = 48 oz. + 8 oz. = 56 oz.

Now, to find the amount needed when the recipe is halved:

• Divide the total ounces by 2: 56 oz. ÷ 2 = 28 oz.

Next, convert 28 ounces back into pounds and ounces:

• Since there are 16 ounces in a pound, divide 28 by 16. There is 1 pound in 16 ounces, which gives you 1 lb. with a remainder.

• 28 oz. - 16 oz. (1 lb.) = 12 oz.

Thus, when halved, the amount of sugar needed is 1 lb. 12 oz. This aligns with the answer option that states 1 lb. 12 oz.
