Created by Sal Khan. Stepby-step solution of converting 3/2 as a mixed number. There are three basic steps to convert an improper fraction to a mixed number: Divide the numerator by the denominator (you can use long division if you want to!) to find out what the quotient and the remainder are. If the fraction is made up of whole numbers, you will always get an . First let us look at whole number exponents: The exponent of a number says how many times to use the number in a multiplication. In this example: 8 2 = 8 × 8 = 64. What about a fractional exponent like 4 3/2? That is really saying to do a cube (3) and a square root (1/2), in any order. Let me explain. awhole number above 1 that cannot be made by multiplying other whole numbers. The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19 and 23, and we have a prime number chart if you need more. When it can be made by multiplying other whole numbers it is a Composite Number. 2 is Prime, 3 is Prime, 4 is Composite (=2×2), 5 is Prime, and so Integers (can be positive or negative) all of the whole numbers (1, 2, 3, etc.) plus all of their opposites (-1, -2, -3, etc.) and also 0. Rational numbers: any number that can be expressed as a fraction of two integers (like 92, -56/3, √25, or any other number with a repeating or terminating decimal) Irrational numbers: all the numbers that Ex1.1, 4 State whether the following statements are true or false. Give reasons for your answers. (i) Every natural number is a whole number. 1, 2,3,4,5 are both natural as well as whole numbers All natural numbers are whole numbers So , True. Next: Ex 1.1, 4 (ii) → Ask a doubt. Stepby-step solution of converting 2/3 as a mixed number. There are three basic steps to convert an improper fraction to a mixed number: Divide the numerator by the denominator (you can use long division if you want to!) to find out what the quotient and the remainder are. If the fraction is made up of whole numbers, you will always get an
