The arrow-head on the right side shows the natural numbers counting upto infinite.
Whole Numbers
Counting numbers including 0 are known as whole numbers. If the counting numbers start from 0, then they include the set of whole numbers. Whole numbers are denoted by W. Therefore,
W= {0, 1, 2, 3, 4, 5,......}
The arrow-head on the right side shows the whole numbers counting up to infinite.
Ascending and Descending Order
Ascending Order
Numbers in a group are said to be in ascending order when they are arranged from the« smallest to the largest number. For example, the ascending order of the numbers: 45, 23, 34, 76, 87, 90 is 23 < 34 < 45 < 76 < 87 < 90.
Descending Order
Numbers in a group are said to be in descending order when they are arranged from the largest to the smallest. For example, the descending order of the number: 56, 34, 46, 23, 55 is\[56>55>46>34>23\].
Face Value and Place Value
We have already learnt about ones, tens and hundreds upto three places. Now, we will learn about the fourth place which is 'thousands' or 1000s. A number with thousands place will have four digits in it.
Face Value of a Digit
The face value of a digit in a number is the value of the digit itself. Therefore, the face value of a number does not change on changing its place. For example, in the number 4673, the face value of 6 is 6. If the digit 6 changes its place from hundreds to tens (4763), then the face value of 6 remains same as 6.
Place value of a Digit
The place value of a digit is the value of where the digit is in the number. The place value of a number changes according to the placement of digits in the number. The place value of 6 in the number 4673 is 600. On changing the place of 6 from 4673 to 4763, the place value of 6 changes from 600 to 60.
Number Facts
2 is the numerator. Now, 2 parts out of 5 parts is being talked about or 1 part is going to be shaded or taken out. Here, the number \[\frac{2}{5}\] is known as fractional number and its symbol \[\frac{2}{5}\] is called a fraction.
Types of Fractions
There are several types of fractions. Let us study the fractions and their types.
Unit Fractions
A fraction, whose numerator is 1, is called a unit fraction. For example, \[\frac{1}{5},\frac{1}{3},\frac{1}{9},\frac{1}{10}\]are unit fractions. Here, the denominators of all fractions are different but numerators are 1.
Like and Unlike Fractions
Fractions in which the denominators are same, are called the like fractions and the fractions in which denominators are different, are called unlike fractions. For example, \[\frac{2}{3},\frac{1}{3},\frac{4}{3}\]are like fractions and \[\frac{2}{5},\frac{7}{4},\frac{3}{8}\] are unlike fractions.
Operations with Fractions
Addition of Like Fractions
Suppose two fractions are \[\frac{1}{5}\] and \[\frac{3}{5}\] and we have to add them.
So, we have, \[\frac{1}{5}+\frac{3}{5}=\frac{1+3}{5}=\frac{4}{5}\]
Therefore, the sum of like fractions \[=\frac{Sum\text{ }of\text{ }Numerators}{Common\text{ }Denominator}\]
Word Problems Based on Fractions
A fraction is defined as a portion of the whole. It is made up of two numbers: Numerator and Denominator. Fraction is a small amount of whole quantity. For example, if a piece of wire is divided into three parts, then each part is one-third part or \[\frac{1}{3}\] part of whole. The word problems involving fractions are usually based on real-life. Let us look at the following problems based on fractions.
Time and Clock
Time is important to plan our day. Time is the ongoing sequence of events. We use time to order events in the past, present and future. Time is passing non-stop. We use a clock or watch to measure time. Time is measured in seconds, minutes, hours, days, weeks, months and years with the help of clocks and calendars.
Indian Currency
Currency is a generally accepted form of money, including coins and paper notes. Different countries uses different currencies. Indian currency is know as Rupees. Symbol for Indian rupees is ‘Rs.’ and Symbol for Indian paise is 'p'. We write 78 rupees as Rs.78 and 50 paise as 50 p. There are 100 paise in one rupee. Suppose we have rupees one hundred four and more... | Plane Shape | Solid Shape |
