Mathematics for Class 5: NCERT

Introduction:
In Class 5, the Mathematics curriculum is designed to provide students with a strong foundation in basic mathematical concepts. The National Council of Educational Research and Training (NCERT) has developed a comprehensive set of textbooks that cover various topics in mathematics.

Division:
Division is a mathematical operation that involves splitting a number into equal parts or groups. It helps in understanding the concept of sharing and distribution. In Class 5, students are introduced to division and learn how to divide two numbers.

Problem:
Let's solve the problem: 243.4 ÷ 8

Method:
To divide a decimal number by a whole number, we follow the following steps:

Step 1: Ignore the decimal point and divide the numbers as whole numbers.
2434 ÷ 8 = 304 remainder 2

Step 2: Bring down the decimal point into the quotient.
The decimal point in 243.4 will be placed after the first digit in the quotient.

Step 3: Divide the remainder by the divisor.
Since we have a remainder of 2, we need to divide 2 by 8.

Answer:
The result of 243.4 ÷ 8 is 30.425.

Conclusion:
Division is an important mathematical operation that helps in solving real-life problems involving sharing and distribution. By following the steps mentioned above, we can easily divide decimal numbers by whole numbers.
