What Is One Eighth as a Fraction with Examples
Meaning of Eighth - How it is Used in Maths and Fraction?
Eighth in the subject of Mathematics can be defined as the sequential number of 8. In another understanding, we can also say that eighth means the fraction in relation to 8 parts. Like ⅛, this will be read as one-eighth of a part.
We will learn more about eighth. The study of eighth will be done by the meaning of fraction, eighth meaning in general, and also the eighth meaning in Math. We will start our discussion with eight meanings in general.
What is Meant by Eighth in General?
The dictionary meaning of eighth is the ordinal number that corresponds to the number 8 in the number system. It also means one of the eight equal parts. The eighth as an ordinal number is positioned before 9 and after 7. The other word for eighth is the octave, which is also used in the musical language.
This was the general meaning of eighth. Now, let us know the eighth meaning in Maths.
Eighth in Mathematics
In the study of Maths, we learn the meaning of eight moreover in the terms of fractions. One-eighth means one part of the equal section of eight parts. Two-eighths mean one quarter and four-eighths make a half section. We use eighths while we split any cake and make them into quarters and then divide each of those quarters in half.
You can understand eighth properly while learning eighth in terms of the fraction. Let us learn the same in the next section.
Eighths in Fraction
Eighth in terms of a fraction means the sequential number of eighths in the number system. Eighths help us understand how many parts are being covered in the whole parts of the eighth. We will present the various fractional forms of eighth which will make our discussion clearer.
Eighths Fractions:
Eight over eight represented as 8/8
1/8 can be read as one-eighth or one over eight.
2/8 can be read as two-eighths or two over eight.
3/8 can be read as three-eighths or three over eight.
4/8 can be read as four-eighths or four over eight.
5/8 can be read as five-eighths or five over eight.
6/8 can be read as six-eighths or six over eight.
7/8 can be read as seven-eighths or seven over eight.
8/8 can be read as eight-eighths or eight over eight.
This was all about a basic study on eighth, you will need this learning especially while you solve fractional sums. Likewise, there are other fractions like fourth, or fifth, all these will be solved similarly. If you would like to practice the sums on this, then you can practice the fractional exercise of one-eighth.
FAQs on Understanding Eighth in Mathematics
1. What is an eighth in math?
An eighth is one of eight equal parts of a whole and is written as the fraction 1/8. In fractions, the numerator 1 shows one part is taken, and the denominator 8 shows the whole is divided into eight equal parts. For example, if a pizza is cut into 8 equal slices, one slice represents 1/8 of the pizza.
2. How do you write one eighth as a fraction?
One eighth is written as the fraction 1/8. The number 1 is the numerator (top number), and 8 is the denominator (bottom number). This means one part out of eight equal parts of a whole.
3. What is 1/8 as a decimal?
The fraction 1/8 as a decimal is 0.125. To convert it, divide 1 by 8: 1 ÷ 8 = 0.125. This decimal form is commonly used in measurements and calculations.
4. What is 1/8 as a percentage?
The fraction 1/8 is equal to 12.5%. To convert a fraction to a percentage, multiply by 100: (1 ÷ 8) × 100 = 12.5%. This shows that one eighth represents 12.5 percent of a whole.
5. How do you find one eighth of a number?
To find one eighth of a number, divide the number by 8. For example:
- One eighth of 40 = 40 ÷ 8 = 5
- One eighth of 64 = 64 ÷ 8 = 8
This method works because 1/8 means dividing a quantity into eight equal parts.
6. What is the meaning of eighth in fractions?
In fractions, an eighth means dividing a whole into eight equal parts and taking one part, written as 1/8. It represents a proper fraction because the numerator (1) is smaller than the denominator (8).
7. What is the difference between 1/4 and 1/8?
The fraction 1/4 is larger than 1/8 because it represents one part out of four equal parts, while 1/8 represents one part out of eight equal parts. Since the whole is divided into more pieces in 1/8, each piece is smaller. In decimal form: 1/4 = 0.25 and 1/8 = 0.125.
8. How many eighths make a whole?
It takes 8 eighths to make one whole. Mathematically, 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 8/8 = 1. This shows that eight equal eighths equal a complete whole.
9. Can you give a real-life example of an eighth?
A real-life example of an eighth is one slice of a cake cut into eight equal pieces, which represents 1/8 of the cake. Other examples include one eighth of an hour (7.5 minutes) or one eighth of a dollar (12.5 cents).
10. How do you multiply a number by 1/8?
To multiply a number by 1/8, divide the number by 8 or multiply it by 1/8. For example:
- 24 × 1/8 = 24 ÷ 8 = 3
- 56 × 1/8 = 56 ÷ 8 = 7
Multiplying by one eighth finds one of eight equal parts of the number.
