Integers Class- 7th RS Aggarwal Exe-1A Goyal Brothers ICSE Math Solution

**Question: 1. Write all integers between :**

**(i) -9 and -3**

**Answer: **To Find:- write all integers between -9 and -3.

Solution:- This question can easily be solved by just writing the integers between two numbers. We have to just write the numbers between two numbers.

= Hence the integers are -8,-7,-6,-5,-4,-3,-2,-1,0,1,2.

**(ii) -33 and -26**

**Answer: **To Find:- write all integers between -33 and -26.

Solution:- This question can easily be solved by just writing the integers between two numbers. We have to just write the numbers between two numbers.

= Hence the integers are −32,−31,−30,−29,−28,−27.

**(iii) -5 and 2**

**Answer: **To Find:- write all integers between -5 and 2.

Solution:- This question can easily be solved by just writing the integers between two numbers. We have to just write the numbers between two numbers.

= Hence the integers are -4, -3, -2, -1, 0, 1.

**(iv) -1 and 6**

**Answer: **To Find:- write all integers between -1 and 6.

= Hence the integers are 0,1,2,3,4,5.

**Question: 2.**** Compare the integers :**

**(i) -16 and -61**

**Answer: **-16 > -61

∴ a > b in positive integers but -a < -b in negative integers

**(ii) -39 and 13**

**Answer:** -39 < 13

∴ every positive number is always greater than any negative number

**(iii) -236 and -362**

**Answer: **-236 > -362

∴ a > b in positive integers but -a < -b in negative integers

**(iv) -2 and 0**

**Answer: **-2 < 0

∴ 0 is greater than every negative number

**Question: 3. Evaluate :**

**(i) 20 – Ι -11 Ι**

**Answer:** Given, 20 – Ι -11 Ι

= 20 – 11 [∴ Ι -11 Ι = 11 (Rule)]

= 9

**(ii) Ι -23 Ι – Ι -16 Ι**

**Answer: **Given, Ι -23 Ι – Ι -16 Ι

= 23 – 16

= 7

**(iii) Ι -137 Ι + Ι -13 Ι**

**Answer: **Given, Ι -137 Ι + Ι -13 Ι

= 137 + 13

= 150

**(iv) 6 – Ι -4 Ι**

**Answer: **Given, 6 – Ι -4 Ι

= 6 – 4

= 2

**Question: 4. Arrange the following integers in ascending order :**

**(i) -9, 11, -23, 41, -37, 0, -5**

**Answer: **Given, -9, 11, -23, 41, -37, 0, -5

Ascending order : −37,<−23,<−9,<-5,<0,<11,<41

= −37, −23, −9, -5, 0, 11, 41.

**(ii) -31, 19, -50, -8, -23, 3, 8**

**Answer: **Given, -31, 19, -50, -8, -23, 3, 8

Ascending order : −50,<−31,<−23,<−8,<3,<8,<19

= −50, −31, −23, −8, 3, 8, 19

**(iii) -2, 12, -43, 31, 7, -35, -10**

**Answer: **Given, -2, 12, -43, 31, 7, -35, -10

Ascending order : −43,<−35,<−10,<−2,<7,<12,<31

= −43, −35, −10, −2, 7, 12, 31

**Question: 5. Arrange the following integers in descending order :**

**(i) -24, 16, -40, -5, -13, 6, -1**

**Answer: **Given: -24, 16, -40, -5, -13, 6, -1

#### Descending order: 16,>6,>−1,>−5,>−13,>−24,>−40

= 16, 6, −1, −5, −13, −24, −40

**(ii) 0, -7, 19, -23, -3, 8, 46**

**Answer: **Given: 0, -7, 19, -23, -3, 8, 46

#### Descending order: 46,>19,>8,>0,>-3,>-7,>-23

= 46, 19, 8, 0, -3, -7, -23

**(iii) -31, -13, -49, 4, 37, -9, -52**

**Answer: **Given: -31, -13, -49, 4, 37, -9, -52

#### Descending order: 37,>4,>-9,>-13,>-31,>-49,>-52

= 37, 4, -9, -13, -31, -49, -52

**Question: 6. Fill in the blanks :**

(i) 0 is grater than every **negative** integer.

(ii) Every negative integer is less than every **positive** integer.

(iii) For any two positive integers a and b, if a < b, then** -a > -b**.

(iv) Modulus of a negative integer is always **positive**.

(v) The largest negative integer is **-1**.

(vi) The smallest positive integer is **1**.
