3. Review
Multiplication of integers
 The product of two integers with the same
sign is positive.
 The product of two integers with different
signs is negative.
Example:
3 x 5 = 15
3 x (-5) = -15

4.  Get 10 pcs of 5 peso coins.
 Share 2pcs of 5 peso coins to your 4
companions.
How many coins are left to you? 2 pcs of 5 peso coin
How many times you share the coins with your companions
including what is left to you?

Motivation

5. 50 ÷ 10
dividend
= 5
divisor quotient
If ab = c c÷ a = b
10 x 5 = 50 50 ÷ 10 = 5

6. Division of Integers

7. 50 ÷ 10
dividend
= 5
divisor quotient
positive positive positive

8. Division of Integers
Rules for division of integers
Rule 1. The quotient of two positive integers is positive.
Example:
4 ÷ 4 = 1
10 ÷ 5 = 2

9. Division of Integers
Rules for division of integers
Rule 2. The quotient of two negative integers is positive.
Example:
-12 ÷ -4 = 3
-15 ÷ -3 = 5

10. Division of Integers
Rules for division of integers
Rule 3. The quotient of two unlike signs is negative.
Example:
-12 ÷ 4 = -3
15 ÷ -3 = -5

11. Lets practice!
Find the value of the following.
1. 18 ÷ 6
2. (-54) ÷ 2
3.100 ÷ (− 4 )
4. (-100) ÷ (-50)
5. (-120) ÷ 4

12. 1. Joan borrowed ₽5.00 a day to buy lunch.
She now owes ₽65.00 how many days did
Joan borrow ₽5.00?
(-65) ÷ (−5) = 13
𝐽𝑜𝑎𝑛 𝑏𝑜𝑟𝑟𝑜𝑤𝑒𝑑 𝑖𝑛 13 𝑑𝑎𝑦𝑠.

13. 2. Mr. Andrews dug a 20 feet deep hole in
his backyard. If he dug 5 feet per hour,
long did it take him?
(-20) ÷ (−5) = 4
𝐼𝑡 𝑡𝑜𝑜𝑘 ℎ𝑖𝑚 4ℎ𝑟𝑠.

17. Quiz
1 whole sheet of paper. Find the value of each of
the following.
1. 20 ÷ 5
2. (-60) ÷ 5
3. 100÷ (-10)
4. (-108) ÷ (-9)
5. (-180) ÷ (-30)
= 4
= −12
= −10
= 12
= 6
