If y’all double three/4 of a loving cup, yous’ll go 6/4 cups, which can exist simplified every bit three/2 cups or ane 1/2 cups. In decimals, 3/4 of a cup is .75 cups, and .75 doubled is 1.5 cups. Since a United States customary loving cup holds exactly 8 U.S. fluid ounces, iii/4 of a cup is exactly 6 ounces. When y’all double 3/4 of a cup, you’ll get 12 U.S. fluid ounces. When following recipes, it is important to note that U.S. customary book measurements are non the same as the British majestic system even though they share the same names for the volume units.

**Fractions**

Getting a mental motion-picture show of fractions when measuring recipe portions may be easy and comes naturally for some, just information technology can be disruptive for others. This result may even be made more complicated past recipe writers who will require calculation or doubling fractions, instead of writing the exact portions in whole numbers. Such recipes will have some home cooks scrambling to take a self-imposed crash form on fractions, wondering how they have forgotten something they mastered dorsum in the third grade.

Fractions are a part of a whole, and information technology is written downwardly with meridian number and a bottom number with a line in between. The pinnacle number is called a “numerator,” and the bottom number is called the “denominator.” Separating these 2 numbers is a division line called a “vinculum.”

**How to Add Fractions**

Calculation fractions is piece of cake. If the fractions have the same denominator, as in the case of iii/4, add the numerators and retain the common denominator, thereby giving you 6/4. If the fractions do not have the same denominator, such equally 1/iii + one/iv, multiply the numerators with the denominators of the other fraction (1×3 + 1×4) and add the results (iii+iv = seven), which becomes your new numerator. Multiply the denominator of the two fractions (3×four), and the result (12) is your new denominator. Thus, 1/3 + ane/4 volition requite you vii/12.

**Improper Fractions**

Doubling or adding 3/4 + 3/4 gives you 6/iv. Fractions with a numerator college than their denominator are called improper fractions. Improper fractions oftentimes represent whole numbers that are greater than ane. Y’all can convert improper fractions into mixed fractions to go far easier for you to understand recipe portions.

**How to Catechumen Improper Fractions to Mixed Fractions**

To convert improper fractions into mixed fractions, divide the numerator past the denominator, in this case, 6 ÷ four = 1 with the remainder two. Write downwardly the whole number 1 write down the rest two as the new numerator over the denominator. Hence, 1 two/4. Simplify the fraction 2/4 to arrive at 1/ii, and you’ll become ane one/2.

Doubling three/4 cups, therefore, will give y’all one i/2 cups. To simplify fractions, split both the numerator and the denominator by 2 until you arrive at numbers where one or both the numerator and denominator can no longer be divided by 2. Some other way to simplify fractions is by dividing both the numerator and denominator past their greatest common factor.

**Converting Fractions in Decimals**

Fractions represent division, which means that dividing the numerator by the denominator gives you its equivalent in decimals. A simple instance is i/2 where 1 ÷ ii = .v. To convert improper fractions to decimals, catechumen it into a mixed fraction as shown before, and and then convert the fraction accompanying the whole number into decimals.

**US Customary vs. British Majestic Systems of Measurement**

As mentioned earlier, a U.S. customary cup holds 8 fluid ounces. Two U.S. cups are equivalent to one U.S. pint, 2 U.S. pints make a U.S. quart, and four quarts is equivalent to a U.S. gallon. The U.S. customary system is different in increments and measurements compared to the purple system even though the units share the same names. An imperial cup holds x regal fluid ounces, 2 imperial cups is equivalent to an majestic pint, 2 imperial pints equal an regal quart, and four imperial quarts equal an majestic gallon. A U.S. fluid ounce is also slightly bigger at 29.573 milliliters (mL) to the 28.412 mL of the imperial fluid ounce.
