Adding 2 ane/three cups gives you two/3 cups. In decimals, 1/3 of a loving cup is .33 cups, so .33 cups plus .33 cups equals .66 cups. The United states customary cup holds 8 fluid ounces. Since one/three or .33 of 8 ounces is 2.64 ounces, two/3 U.S. fluid cups or 1/3 U.South. cups plus 1/3 U.S. cups is equivalent to 5.28 U.Southward. fluid ounces. The British imperial loving cup holds 10 purple ounces. This means that i/3 or .33 of 10 ounces is 3.3 ounces. Thus, 1/3 imperial cups plus 1/3 imperial cups is 6.half dozen ounces.
What Are Fractions?
Fractions are defined as a part of a whole, written with a pinnacle number chosen a numerator, and a bottom number is chosen the denominator. A division line called a vinculum separates the numerator and denominator in fractions.
Fractions are often presented with a numerator of a lower number than the denominator. However, there are fractions with numerators that are greater than their denominators. Such fractions are called “improper fractions.” Improper fractions may be converted into mixed fractions, which is a whole number accompanied past a fraction, such as in 1 1/2.
Adding fractions is like shooting fish in a barrel. With fractions that have an identical denominators such as in 1/3 + 1/3, add the numerators and retain the denominator. Thus one/three + 1/3 = two/3. In fractions that don’t take an identical denominator, such every bit in 1/2 + 1/iii, multiply the numerators with the denominators of the other fraction, and and then add the results which volition exist your new numerator.
Since multiplying 1×ii gives you 2 and i×iii gives yous three, adding 2+3 will give you 5, which becomes your new numerator. Next, multiply the denominators of the two fractions, and the result will be your new denominator. Thus, 1/two + one/3 equals v/6.
Converting Fractions to Decimals
Fractions resemble division formulas considering they represent division. In other words, one/three means one÷iii, which gives you 0.33. 1/3 cups, therefore, is equivalent to .33 cups and 0.33 cups plus .33 cups equals .66 cups.
Cups in U.S. Customary and British Royal Systems
Both the U.Southward. customary and British majestic organization units of measurements are based on the former English arrangement. While the units measurements for length, weight, distance, and area are identical in both the U.South. customary and majestic systems, their units for book such as fluid ounces, cups, pints, quarts, and gallons differ.
Using the metric system for volume every bit reference, a U.S. fluid ounce is equivalent to 29.573 milliliters (mL). Since a U.South. fluid cup holds eight fluid ounces, one U.Due south. cup holds 236.48 mL ― 1/3 or .33 of which is 78.04 mL. This makes 2/3 of a cup equivalent to 156.07.
The royal fluid ounce holds 28.413 ml. Since ane majestic cup holds 10 imperial fluid ounce, one imperial cup is equivalent to 284.xiii mL. Using the aforementioned calculations every bit above, 1/3 of an regal cup is 93.76 mL, and ii/three of an majestic cup is equivalent to 187.52 mL.
The Metric System Cup
Although seldom used, the metric arrangement also has its own version of the loving cup. I metric system cup measures 250 mL. One-3rd of a metric system loving cup is 82.5 mL. Therefore, 1/3 metric organization cup plus 1/3 metric organization cup equals ii/3 metric system cups, which is 165 mL.
