**DAV Class 5 Maths Chapter 7 Worksheet 8 Notes**

In order to divide a decimal number by 10, 100, 1000 we just shift the decimal point in the quotient to the left by as many places as there are zeroes in the divisor.

Examples:

(a) 76.9 ÷ 10 = 7.69

The decimal point shifts one place to the left.

(b) 349.6 ÷ 100 = 3.496

The decimal point shifts two places to the left.

(c) 756.3 ÷ 1000 = 0.7563

The decimal point shifts three places to the left.
