## Karnataka Board Class 8 Maths Chapter 1 Playing with Numbers Ex 1.1

Question 1.

Write the following numbers in generalized form 39, 52, 106, 359, 628, 3458, 9502, 7000.

Answer:

39 = 30 + 9 = (3 × 10) + (9 × 1)

52 = 50 +2 = (5 × 10) + (2 × 1)

106 = 100 + 6 = (1 × 100) + (0 × 10)+(6 × 1) 359 = 300 + 50 + 9 = (3 × 100) + (5 × 10) + (9 × 1)

628 = 600 + 20 + 8 = (6 × 100) + (2 × 10) + (8 × 1)

3458 = 3000 + 400 + 50 + 8 = (3 × 1000) + (4 × 100) + (5 × 10) + (8 × 1)

9502 = 9000 + 500 + 2 = (9 × 1000) + (5 × 100) + (0 × 10) + (2 × 1)

7000 = 7000 + 0 + 0 + 0 = (7 × 1000) + (1 × 100) + (0 × 10) + (0 × 1)

Question 2.

Write the following in the decimal form.

(i) (5 × 10) + (6 × 1);

(ii) (7 × 100)+ (5 × 10)+ (8 × 1);

(iii) (6 × 1000) + (5 × 10) + (8 × 1);

(iv) (7 × 1000) + (6 × 1);

(v) (1 × 1000) + (1 × 10);

Answer:

(i) (5 × 10) + (6 × 1);

50 + 6 = 56

(ii) (7 × 100) + (5 × 10)+ (8 × 1);

700 + 50 + 8 = 758

(iii) (6 × 1000) + (5 × 10) + (8 × 1);

6000 + 50 + 8 = 6058

(iv) (7 × 1000) + (6 × 1);

7000 + 6 = 7006

(v) (1 × 1000) + (1 × 10);

1000 + 10 = 1010
