Divide by 10

Key Notes :

Understanding Division

• Division is splitting a number into equal parts.
• When dividing by 10, we find how many groups of 10 are in a number.

Basic Rule of Dividing by 10

• When a number is divided by 10, the digits shift one place to the right.
• Example: 50 ÷ 10 = 5, 120 ÷ 10 = 12.

Using Place Value

• The last digit (ones place) moves to the right, and the number becomes 10 times smaller.
• Example: 430 ÷ 10 = 43 (the zero is removed).

Dividing Whole Numbers by 10

• Any whole number ending in zero will become a smaller whole number.
• Example: 90 ÷ 10 = 9.

Dividing Numbers Without Zero

• Numbers not ending in zero will have a decimal answer.
• Example: 7 ÷ 10 = 0.7.

Shortcut Trick

• Remove the last zero when dividing a number by 10 (if present).
• Example: 250 ÷ 10 = 25.

Real-Life Examples

• Sharing 100 candies among 10 friends: Each gets 10 candies (100 ÷ 10 = 10).
• Distributing 50 pencils among 10 students: Each student gets 5 pencils (50 ÷ 10 = 5).

Remember how to divide by 10:

10 ÷ 10 = 1 20 ÷ 10 = 2 30 ÷ 10 = 3 40 ÷ 10 = 4 50 ÷ 10 = 5 60 ÷ 10 = 6 70 ÷ 10 = 7 80 ÷ 10 = 8 90 ÷ 10 = 9 100 ÷ 10 = 10
