What is a Fraction?
A fraction (from Latin fractus, “broken”) represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A common, vulgar, or simple fraction (examples: 1/2, 2/4, 3/5) consists of an integer numerator displayed above (or before) a line (or a slash /) and an integer denominator displayed below (or after) the line. Numerators and denominators are also used in fractions that are not common (examples: 2 1/2 = 21/2 = 9/4).
What is the Definition of a Fraction?
A fraction (from Latin fractus, “broken”) represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A common or simple fraction consists of an integer numerator displayed above (or before) a line ( or ), and a non-zero integer denominator, displayed below (or after) that line. Numerators and denominators are also used in fractions that are not common, including compound fractions, complex fractions, and mixed numerals.
What is a Mixed Number?
When we talk about mixed numbers, we are talking about a whole number and a fraction combined. For example, if I have 2 apples and eat 1/2 of one, I have eaten a mixed number – 2 1/2 apples. We could also write this as 2 + 1/2, or 21/2.
Mixed numbers make more sense when we are talking about things that are being taken away – like in the example above. If I start with 2 apples, and eat 1/2 of one, then I am left with 1 1/2 apples. This is easier to understand than if we were to say that I have 1.5 apples (one and a half apples).
To change a mixed number into an improper fraction, all we need to do is multiply the whole number part by the denominator (bottom number) of the fraction, and then add that to the numerator (top number) of the fraction. So in our example above, 2 x 2 would be 4, + 1 would be 5, so our improper fraction would be 5/2.
What is an Improper Fraction?
An improper fraction is a fraction in which the numerator (top number) is greater than or equal to the denominator (bottom number). For example, in the fraction 3/2, the numerator, 3, is greater than the denominator, 2.
An improper fraction can be converted to a mixed number by division. For example, the improper fraction 3/2 can be converted to 1 1/2 (one and one-half) by division:
3 ÷ 2 = 1 remainder 1
2
The answer is 1 with a remainder of 1. This can be written as a mixed number as follows:
1 + (1/2) = 1 1/2
What is a Proper Fraction?
A proper fraction is a fraction where the numerator (top number) is less than the denominator (bottom number).
For example:
1/2 is a proper fraction. Here, 1 is less than 2.
3/4 is a proper fraction. Here, 3 is less than 4.
7/8 is a proper fraction. Here, 7 is less than 8.
An improper fraction is a fraction where the numerator (top number) is greater than or equal to the denominator (bottom number).
For example:
4/3 is an improper fraction because 4 is greater than 3.
5/5 is an improper fraction because 5 is equal to 5.
What is a Decimal?
A decimal is a fraction (one number after the decimal point) expressed as a percent. For example, 0.35 can be expressed as 35%.
What is a Percent?
A percent is a value expressed as a fraction of 100. It is denoted using the percent sign, “%”, or sometimes as “pct.” For example, 35% is equal to the decimal 0.35, which in turn is equal to the fraction 35/100. To find 35% of a value, multiply the original value by 0.35.
Percentages can be expressed as decimals or fractions. To convert from a decimal to a percentage, multiply by 100. To convert from a percentage to a decimal, divide by 100, and remove the “%” sign if present.
One way to express a fraction as a percentage is to first convert it to a decimal (if it is not already), then multiply by 100 and add the “%” sign. Another way to express a fraction as a percentage is to first convert it both the numerator and denominator to whole numbers that are multiples of 10, then express it as an improper fraction (i.e., with a numerator greater than the denominator), and finally multiply by 10 and add the “%” sign
What is an Exponent?
An exponent is a number that tells how many times the base number is used as a factor. In the expression 5^3, 5 is the base and 3 is the exponent. The exponent shows that the base is used 3 times as a factor. When no exponent is written, it is understood to be 1. So 5^1 = 5.
What is a Square Root?
In mathematics, a square root of a number x is a number y such that y2 = x; in other words, a number y whose square (the result of multiplying the number by itself, or y × y) is x. For example, 4 and −4 are square roots of 16 because 42 = (−4)2 = 16. Every nonnegative real number x has a unique nonnegative square root, called the principal square root, which is denoted by √x, where the symbol √ is called the radical sign or radix. For example, the principal square root of 9 is 3 denoted by √9 = 3, because 32 = 3 · 3 = 9 and 3 is nonnegative.
What is 2 as a Fraction?
2 as a fraction is 2/1 or 2. This means that there are 2 parts of whatever you’re measuring, and each part is equal to 1/1 or 1. So, if you’re measuring something like pizza, 2/1 would be 2 pizzas.
