2 3 Plus 1 3

Adding two 1/3 cups gives you 2/3 cups. In decimals, 1/iii of a cup is .33 cups, and then .33 cups plus .33 cups equals .66 cups. The United States customary loving cup holds 8 fluid ounces. Since 1/3 or .33 of 8 ounces is ii.64 ounces, two/iii U.S. fluid cups or i/3 U.Southward. cups plus i/3 U.Southward. cups is equivalent to v.28 U.S. fluid ounces. The British imperial cup holds 10 majestic ounces. This means that ane/3 or .33 of 10 ounces is 3.3 ounces. Thus, 1/3 imperial cups plus one/3 imperial cups is 6.6 ounces.

What Are Fractions?

Fractions are defined as a function of a whole, written with a top number chosen a numerator, and a lesser number is called 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. Yet, at that place are fractions with numerators that are greater than their denominators. Such fractions are called "improper fractions." Improper fractions may exist converted into mixed fractions, which is a whole number accompanied past a fraction, such every bit in 1 1/ii.

Adding Fractions

Adding fractions is easy. With fractions that have an identical denominators such as in i/iii + 1/three, add together the numerators and retain the denominator. Thus i/three + 1/iii = ii/3. In fractions that don't have an identical denominator, such as in one/2 + 1/3, multiply the numerators with the denominators of the other fraction, and then add the results which will be your new numerator.

Since multiplying 1×2 gives yous 2 and 1×3 gives yous 3, adding ii+3 will give y'all 5, which becomes your new numerator. Next, multiply the denominators of the two fractions, and the outcome will be your new denominator. Thus, 1/ii + i/3 equals 5/vi.

Converting Fractions to Decimals

Fractions resemble division formulas because they represent division. In other words, i/3 means 1÷3, which gives you 0.33. 1/three cups, therefore, is equivalent to .33 cups and 0.33 cups plus .33 cups equals .66 cups.

Cups in U.South. Customary and British Imperial Systems

Both the U.S. customary and British royal system units of measurements are based on the old English language system. While the units measurements for length, weight, altitude, and expanse are identical in both the U.Due south. customary and purple systems, their units for volume such every bit fluid ounces, cups, pints, quarts, and gallons differ.

Using the metric organisation for volume as reference, a U.South. fluid ounce is equivalent to 29.573 milliliters (mL). Since a U.South. fluid loving cup holds viii fluid ounces, one U.S. cup holds 236.48 mL ― 1/three or .33 of which is 78.04 mL. This makes two/3 of a cup equivalent to 156.07.

The imperial fluid ounce holds 28.413 ml. Since 1 imperial cup holds 10 imperial fluid ounce, 1 imperial cup is equivalent to 284.13 mL. Using the same calculations every bit above, 1/3 of an majestic cup is 93.76 mL, and 2/iii of an royal loving cup is equivalent to 187.52 mL.

The Metric System Loving cup

Although seldom used, the metric organization too has its own version of the cup. One metric organisation cup measures 250 mL. One-tertiary of a metric system cup is 82.v mL. Therefore, one/iii metric system loving cup plus i/3 metric system cup equals 2/3 metric organisation cups, which is 165 mL.
