Write the first five multiples of the following numbers : (i) 7 (ii)

1.	Write the first five multiples of the following numbers : (i) 7 (ii) 12 (iii) 17 (iv) 15 (v) 18
Answer» (i) First five multiples of 7 7 × 1 = 7 7 × 2 = 14 7 × 3 = 21 7 × 4 = 28 7 × 5 = 35 Thus, first five multiples of 7, are 7. (ii) First five multiples of 12 12 × 1 = 12 12 × 2 = 24 12 × 3 = 36 12 × 4 = 48 12 × 5 = 60 Thus first five multiples of 12 are 12. 24, 36, 48 and 60. (iii) First five multiples of 17 17 × 1 = 17 17 × 2 = 34 17 × 3 = 51 17 × 4 = 68 17 × 5 = 85 Thus, first five multiples of 17 are 17, 34, 51, 68 and 85. (iv) First five multiples of 15 15 × 1 = 15 15 × 2 = 30 15 × 3 = 45 15 × 4 = 60 15 × 5 = 75 Thus, first five multiples of 16 are 15, 30, 45, 60 and 75. (v) First five multiples of 18 18 × 1 = 18 18 × 2 = 36 18 × 3 = 54 18 × 4 = 72 18 × 5 = 90 Thus, first five multiples of 18 are 18, 36, 54, 72 and 90.

Write the first five multiples of the following numbers : (i) 7 (ii) 12 (iii) 17 (iv) 15 (v) 18

Answer»

(i) First five multiples of 7

7 × 1 = 7

7 × 2 = 14

7 × 3 = 21

7 × 4 = 28

7 × 5 = 35

Thus, first five multiples of 7, are 7.

(ii) First five multiples of 12

12 × 1 = 12

12 × 2 = 24

12 × 3 = 36

12 × 4 = 48

12 × 5 = 60

Thus first five multiples of 12 are 12. 24, 36, 48 and 60.

(iii) First five multiples of 17

17 × 1 = 17

17 × 2 = 34

17 × 3 = 51

17 × 4 = 68

17 × 5 = 85

Thus, first five multiples of 17 are 17, 34, 51, 68 and 85.

(iv) First five multiples of 15

15 × 1 = 15

15 × 2 = 30

15 × 3 = 45

15 × 4 = 60

15 × 5 = 75

Thus, first five multiples of 16 are 15, 30, 45, 60 and 75.

(v) First five multiples of 18

18 × 1 = 18

18 × 2 = 36

18 × 3 = 54

18 × 4 = 72

18 × 5 = 90

Thus, first five multiples of 18 are 18, 36, 54, 72 and 90.
