CHECKING THE ANSWER

Divisor X Quotient + Remainder = Dividend

DIVISION (ORALLY)

• DIVIDING A NO. BY 10 WHEN A NO. IS DIVIDED BY 10, THE QUOTIENT IS OBTAINED BY REMOVING THE 1^st DIGIT FROM RIGHT. THE DIGIT REMOVED IS THE REMAINDER.

DIVISION (ORALLY)

• DIVIDING A NO. BY 100: When a no. is divided by 100, the quotient is obtained by removing the 1^st 2 digits from right. The digits removed is the remainder.

Division (Orally)

Dividing a no. by 1000: When a no. is divided by 1000, the quotient is obtained by removing the 1^st 3 digits from right. The digits removed is the remainder.

WORD PROBLEMS

We need to do division in many situations in our daily life. Let us study some examples.
Example 1: The cost of 5 pens of the same type is ₹ 75. Find the cost of 1 pen.
Solution: Cost of 5 pens = ₹ 75
Cost of 1 pen = ₹ 75 $\div$ 5

= ₹ 15 

Therefore, the cost of 1 pen is ₹ 15.

Word Problems

Example 2: The annual salary of Raman is ₹ 1,57,620. Find his monthly salary.
Solution: Raman's annual salary = ₹ 1,57,620
One Year = 12 months
His monthly salary = ₹ 1,57,620  $\div$  12

= ₹ 13,135
Therefore, Raman's monthly salary is ₹ 13,135.
