You are watching: 2/3 cup plus 2/3
Fractions are defined as a component of a whole, written v a optimal number referred to as a numerator, and a bottom number is called the denominator. A department line called a vinculum off the numerator and also denominator in fractions.
Fractions are frequently presented v a molecule of a reduced number than the denominator. However, there room fractions through numerators the are greater than your denominators. Such fractions are referred to as "improper fractions." wrong fractions might be converted right into mixed fractions, i m sorry is a whole number attach by a fraction, such together in 1 1/2.
Adding fractions is easy. With fractions that have actually an the same denominators such together in 1/3 + 1/3, include the numerators and retain the denominator. Thus 1/3 + 1/3 = 2/3. In fractions that don"t have an similar denominator, such as in 1/2 + 1/3, multiply the numerators with the denominators of the other fraction, and then include the results which will certainly be your brand-new numerator.
Since multiply 1x2 gives you 2 and 1x3 gives you 3, including 2+3 will give you 5, which i do not care your new numerator. Next, multiply the denominators of the two fractions, and the result will be your brand-new denominator. Thus, 1/2 + 1/3 equals 5/6.
Converting fractions to Decimals
Fractions resemble department formulas since they stand for division. In various other words, 1/3 means 1÷3, which gives you 0.33. 1/3 cups, therefore, is identical to .33 cups and also 0.33 cup plus .33 cups equates to .66 cups.
Cups in U.S. Customary and also British imperial Systems
Both the U.S. Customary and also British imperial system units of measurements are based upon the old English system. While the units dimensions for length, weight, distance, and area are similar in both the U.S. Customary and also imperial systems, their systems for volume together as liquid ounces, cups, pints, quarts, and gallons differ.
Using the metric device for volume as aufdercouch.net, a U.S. Fluid ounce is indistinguishable to 29.573 milliliters (mL). Since a U.S. Fluid cup holds 8 fluid ounces, one U.S. Cup holds 236.48 mL ― 1/3 or .33 of i beg your pardon is 78.04 mL. This makes 2/3 of a cup indistinguishable to 156.07.
The imperial fluid ounce holds 28.413 ml. Because 1 imperial cup holds 10 imperial liquid ounce, 1 imperial cup is identical to 284.13 mL. Using the same calculations as above, 1/3 of an imperial cup is 93.76 mL, and 2/3 of an royal cup is identical to 187.52 mL.

The Metric mechanism Cup
Although seldom used, the metric system additionally has its own version the the cup. One metric device cup actions 250 mL. One-third that a metric device cup is 82.5 mL. Therefore, 1/3 metric system cup add to 1/3 metric mechanism cup equates to 2/3 metric device cups, which is 165 mL.
