Two or more and we use ‘thirds’; hence, ‘two-thirds’ is the correct usage. Quite correct, but it should be noted that the hyphen is not always used: The motion was carried by a two-thirds majority.

Decimal and Fraction Conversion

1. two-thirds – two of three equal parts of a divisible whole. common fraction, simple fraction – the quotient of two integers.

A California injured worker is entitled to receive two-thirds of his pretax gross wages, as set by state law, up to the maximum allowable. Many self-insured public entities and some companies make up the salary difference so that a worker still receives his regular income after sustaining an on-the-job injury.

The integers are the set of whole numbers and their opposites. Fractions and decimals are not included in the set of integers. For example, 2,5,0,−12,244,−15 and 8 are all integers. The numbers such as 8.5,23 and 413 are not integers.

The s…” The set of whole numbers is {0,1,2,3,4,…}. The set of integers is {…,-4,-3,-2,-1,0,1,2,3,4,…}. From these two sets, we can see that every whole number is an integer, but not every integer is a whole number.

An integer (pronounced IN-tuh-jer) is a whole number (not a fractional number) that can be positive, negative, or zero. Examples of integers are: -5, 1, 5, 8, 97, and 3,043. Examples of numbers that are not integers are: -1.43, 1 3/4, 3.14, . 09, and 5,643.1.

−3 obviously falls in this category. Rational numbers are numbers that can be expressed as a fraction or ratio of two integers. Rational numbers are denoted Q . Since −3 can be written as −31 , it could be argued that −3 is also a real number.

Since the numbers 3 and 5 lie between 2 and 7 i.e., between (√2)2 and (√7)2, therefore, √3 and √5 lie between √2 and √7. Hence two irrational numbers between √2 and √7 are √3 and √5.

In mathematics, a field is a set on which addition, subtraction, multiplication, and division are defined and behave as the corresponding operations on rational and real numbers do. The best known fields are the field of rational numbers, the field of real numbers and the field of complex numbers.

34 is a rational number because it can be expressed as the quotient of two integers: 34 ÷ 1.

The square root of 34 is a rational number if 34 is a perfect square. It is an irrational number if it is not a perfect square. Since 34 is not a perfect square, it is an irrational number.

The square root of 34 is expressed as √34 in the radical form and as (34)½ or (34)0.5 in the exponent form….Square Root of 34 in radical form: √34.
