**New Learning Composite Mathematics SK Gupta Anubhuti Gangal Class 6 Whole Numbers Self Practice 2C Solution**

**(1)** (a) 5973 ÷ 1 = 5973

(b) 0 ÷ 675 = 0

(c) 9087 ÷ 9087 = 1

(d) 100 – (593 ÷ 593)

= 100 – 1

= 99

(e) 500 ÷ (98 – 48)

= 500 ÷ 50

= 500 /50

= 10

(f) 0 ÷ (880 ÷ 880)

= 0 ÷ 1

= 0

(g) 2345 ÷ (2345 ÷ 2345)

= 2345 ÷ 1

= 2345

(h) 786 ÷ 786

= 1

(i) 859 ÷ 859

= 1

(j) (790 – 790) ÷ (790 ÷ 1)

= 0 ÷ 790

= 0

**(2)** (a) False

(b) True

(c) False

(d) True

(e) False as because it is meaningless.

**(3)** (a) 0 ÷ a = 0

∴ a = any number

Eg – 0 ÷ 2 = 0

0 ÷ 14 = 0

(b) 62 ÷ 62 = n

∴ n = 1

(c) a ÷ 19 = 0

∴ a = 0

(d) m ÷ 876 = 0

∴ m = 0

(e) 0 ÷ 2058

∴ x = 0

(f) (85 – 34) ÷ n = 3

Or, 51 ÷ n = 3

∴ n = 51/3 = 17

(g) (81 ÷ 9) x n = 9

or, 9 x n = 9

∴ n = 9/9

= 1

(h) 2958 ÷ 2958 + 0 ÷ 2958 – n

or, 1 + 0 ÷ 2958 = x

or, 1 + 0 = x

∴ x = 1

**(4)** (a) 98 x 12 – 78 x 12

= (98 x 12) – (78 x 12)

= 1176 – 936

= 240

(b) 10000 ÷ 100 ÷ 100

= (10000 ÷ 100) ÷ 100

= 100 ÷ 100

= 1

Hii

Hi
