Are you in Class 7 and struggling with rational numbers? With this comprehensive worksheet, you can make the process of mastering rational numbers much more efficient. Learn the basics of adding, subtracting, multiplying and dividing rational numbers in an easy and fun way!
Simplifying Rational Numbers.
Simplifying rational numbers by regrouping them is an important part of understanding rational numbers. To simplify a fraction, you need to first divide the numerator and denominator with their common factor. Once you have simplified the fraction, you can use algebraic properties like addition, subtraction, multiplication and division to combine or simplify it further
Adding and Subtracting Rational Numbers.
This question type requires you to use the basic algebraic properties and the concept of ‘like terms’ to add or subtract rational numbers. To add two rationals, add their numerators and keep their denominators unchanged. Similarly, when subtracting two rationals, just subtract their numerators while keeping the denominators same. When combining unlike fractions, find the least common denominator of both fractions and then proceed with addition or subtraction.
Multiplying and Dividing Rational Numbers.
In order to multiply two rational numbers, you will need to convert them into equivalent fractions by multiplying the numerator and denominator of both fractions by the same number. This means that you must multiply the numerators together, and also multiply their denominators together. When it comes to division of rational numbers, remember that when you divide two rationals by each other, the resulting fraction will be equal to its multiplicative inverse (inverse fractions). To make sense of this rule, start with reducing both numbers into simplest form and then divide accordingly.
Ordering Rational Numbers on a Number Line.
To understand the concept of ordering rational numbers on a number line, it is important to remember that a rational number is any number which can be written in the form of a fraction. When it comes to plotting a series of rational numbers on a number line, the first step is to identify the largest and smallest values and then plot these two points. Then, you can draw an arrow from one point to another joining all the dots in sequence. This will help you visualize and compare each fraction’s relative position on the number line.
Converting Rational Numbers in Simplest Form into Decimals, Fractions and Terminating Decimals.
Converting rational numbers into different forms can help you better understand how fractions and decimals relate to each other. For example, if you were given the fraction 5/8, you could convert it into a decimal by dividing 8 into 5 and converting it to 0.625. Similarly, if you are given 0.625 as a decimal number , then divide 5 by 8 to get back the fraction 5/8 in its simplest form. All terminating decimals can also be expressed as fractions and vice versa.

Q: How to add and subtract rational numbers in Class 7?
A: To add and subtract rational numbers, we need to first find a common denominator. We can then add or subtract the numerators and simplify the result. For example, to add 1/2 and 2/3, we can find a common denominator of 6, and get (3+4)/6 = 7/6.
Q: How to multiply and divide rational numbers in Class 7?
A: To multiply and divide rational numbers, we can simply multiply or divide the numerators and denominators. For example, to multiply 2/3 and 3/4, we can get (23)/(34) = 6/12 = 1/2. To divide 1/2 by 3/4, we can multiply by the reciprocal of 3/4, which is 4/3, and get (1/2) * (4/3) = 4/6 = 2/3.
Q: How to convert rational numbers to decimals in Class 7?
A: To convert rational numbers to decimals, we can simply divide the numerator by the denominator using long division. For example, to convert 2/3 to a decimal, we can get 0.6666... by dividing 2 by 3.
Q: How to compare rational numbers in Class 7?
A: To compare rational numbers, we can convert them to a common denominator and compare their numerators. For example, to compare 2/3 and 3/4, we can find a common denominator of 12, and get 8/12 and 9/12. Since 9/12 is greater than 8/12, we can say that 3/4 is greater than 2/3.
Q: What are some real-life applications of rational numbers in Class 7?
A: Rational numbers are used in many real-life situations, such as measuring ingredients for recipes, calculating distances, and determining time intervals. They are also used in finance and accounting to calculate interest rates and percentage changes.
