Question

A cup of water holds about 8 ounces is a recipe calls for 1/3 cup of water which is the best estimate of the number of ounces that are needed draw a bar diagram if necessary

Answer 1

1/3 cup is approximately equal to 2.67 ounces

Step-by-step explanation:

In cooking and baking, recipes often use measurements that are different from the standard units of measurement used in daily life. One such measurement is the cup, commonly used to measure liquids like water, milk, and oil. A cup of water typically equals 8 fluid ounces in the United States.

If a recipe calls for 1/3 cup of water, we need to convert this measurement into ounces to know how much water is needed. To do this, we can use the fact that 1 cup is equal to 8 ounces.

To convert 1/3 cup to ounces, we can multiply the number of cups by the number of ounces in one cup. That is:

1/3 cup * 8 ounces/cup = 8/3 ounces

However, 8/3 ounces is not a convenient number to work with, so we need to round it to a more practical value. One reasonable approximation for 8/3 is 2.67. Therefore, we can say that 1/3 cup equals approximately 2.67 ounces.

This approximation is reasonable because it is close to the exact value of 8/3 ounces. Using 2.67 ounces as an estimate for 1/3 cup of water in a recipe should provide a good approximation of the water needed.

Answer 2

One-third cup of water is equivalent to approximately 2.67 ounces (8 ounces divided by 3).

Here is a bar diagram to illustrate this:
