Grade: 5-a Lesson: S3-L4

Explanation: The best way to understand decimals is by looking at some examples. Take turns and read each example for easy understanding.

Examples:

Find the division of decimal 54.27 ÷ 9.

Step 1a

First, multiply the dividend and divisor with 100 then we get 5427 ÷ 900.

$1a$

Explanation: In this step, first, convert the decimal number into a whole number, so multiply the dividend and divisor by 100, and then we get 5427 ÷ 900.

Step 1b

Divide the first digit of the dividend (5) by the divisor (900). Since 5 is less than 900, we need to consider the next digits as well. Here, 5427 ÷ 900 then we get a quotient of 6 with a remainder of 27.

$1b$

Explanation: In this step, to divide 5427 by 900, we divide the first digit of the dividend- 5, by 900. Since 5 is less than 900, we consider the next digits as well. We get a quotient of 6 and a remainder of 27.

Step 1c

The new dividend value is 27. If the dividend is less than the divisor, place two zeroes and divide. Divide 2700 by 900. The quotient is 3 with no remainder.

$1c$

Explanation: In this step, the new dividend value is 27. If it’s less than the divisor, place two zeroes, then divide. Divide 2700 by 900. The quotient is 3 with no remainder.

Step 1d

Therefore, 54.27 ÷ 9 = 6.03

$1d$

Explanation: Hence, the result of dividing 54.27 by 9 is equal to 6.03.
