## Access **RS Aggarwal Solutions Class 7 Maths Chapter 1 Exercise 1.3**

**Question 1.****Solution:**

(i) 65 by -13 = 65 ÷ (-13) = -5

(ii) -84 by 12 = -84 ÷ 12 = -7

(iii) -76 by 19 = -76 ÷ 19 = -4

(iv) -132 by 12 = -132 ÷ 12 = -11

(v) -150 by 25 = -150 ÷ 25 = -6

(vi) -72 by -18= -72 ÷ (-18)

(vii) -105 by -21 = -105 ÷ (-21) = 5

(viii) -36 by -1 = -36 ÷ (-1) = 36

(ix) 0 by -31 = 0 ÷ (-31) = 0

(x) -63 by 63 = -63 ÷ 63 = -1

(xi) -23 by -23 = -23 ÷ (-23)

(xii) -8 by 1 = -8 ÷ 1 = -8

**Question 2.****Solution:**

(i) 72 ÷ (………) = -4

⇒ 72 ÷ (-4) = -18

72 + (-18) = -4

(ii) -36 ÷ (………) = -4

⇒ -36 ÷ (-4) = 9

-36 ÷ (9) = -4

(iii) (………) ÷ (-4) = 24

⇒ -4 x 24 = -96

(-96) ÷ (-4) = 24

(iv) (……….) ÷ 25 = 0

(…….) ÷ 25 = 0 {0 ÷ a = 0}

(v) (………) ÷ (-1) = 36

⇒ 36 x (-1) = -36

(-36) ÷ (-1) = 36

(vi) (………..) + 1 = 37

⇒ (-37) x 1 = -37

(-37) ÷ 1 = -37

(vii) 39 ÷ (……….) = -1

⇒ 39 ÷ (-1) = -39

39 ÷ (-39) = -1

(viii) 1 ÷ (………) = -1

⇒ -1 ÷ 1 = -1

1 ÷ (-1) = -1

(ix) -1 + (………) = -1

-1 ÷ (1) = -1

**Question 3.****Solution:**

(i) True : as zero divided by non zero integer is zero.

(ii) False : as division by zero is not meaning full

(iii) False : as (-5) ÷ (-1) = 5 (product will be positive)

(iv) True : as -a ÷ 1 = -a

(v) False : as (-1) ÷ (-1) = 1

(vi) True.

**What is the “Division of integers”?**

To understand the “Division of integers” in a simple manner, it can be defined as the operation which is the reverse of “Multiplication of integers”. It is a method to make evident that for how many times a certain number is stored in another number. There is only one difference here, that in the “Division of integers”, there is no surety that the quotient will be an integer always.

For Example.,

In the question, 88 ÷ 11 = 8

Here, if you want to know that how many times 11 is stored in 88, then the answer will be 8 times.

Continue grasping the techniques we have mentioned in this article to understand the rules on “Division of integers”.

Please take note of the following things:

- Quotient × Divisor = Dividend
- Dividend ÷ Divisor = Quotient
- Dividend ÷ Quotient = Divisor

**RS Aggarwal Solutions Class 7 Maths Chapter 1 Exercise 1.3, ****“Division of integers” – RULES**

**RULE 1:** According to rule 1,

Positive ÷ Negative = Negative

It means that the division of the Numerator being positive and the denominator being negative leads to the negative result. So if the dividend is positive and the divisor is negative then the quotient ideally will be negative.

For Example.,

33 ÷ (-11) = -3

**RULE 2:** According to rule 2,

Positive ÷ Positive = Positive

It means that the division of the two positive integers is always positive in the result. So if the dividend and the divisor are positive then the quotient ideally will be positive.

For Example.,

33 ÷ 11 = 3

**RULE 3:** According to rule 3,

Negative ÷ Positive = Negative

It means that the division of the Numerator being negative and the denominator being positive leads to the negative result. So if the dividend is negative and the divisor is positive then the quotient ideally will be negative.

For Example.,

(-33) ÷ 11 = -3

**RULE 4:** According to rule 4, Negative ÷ Negative = Positive

It means that the division of two negative integers leads to a negative result. So if the dividend and the divisor both are negative then the quotient ideally will always be positive.

For Example.,

(-33) ÷ (-11) = 3
