Answer:

                (a) Multiples of 5, 5 \[\times \] 1 = 5; 5 \[\times \] 2 = 10; 5 \[\times \] 3 = 15; 5 \[\times \] 4 = 20; 5 \[\times \] 5 = 25 \[\therefore \] First five multiples of 5 are 5, 10, 15, 20 and 25. (b) Multiples of 8, 8 \[\times \]1 = 8; 8 \[\times \] 2 = 16; 8 \[\times \] 3 = 24; 8 \[\times \] 4 = 32; 8 \[\times \] 5 = 40 \[\therefore \]First five multiples of 8 are 8, 16, 24, 32 and 40. (c) Multiples of 9, 9 \[\times \] 1 = 9; 9 \[\times \] 2 = 18; 9 \[\times \] 3 =27; 9 \[\times \] 4 = 36; 9 x 5 = 45 \[\therefore \]First five multiples of 9 are, 9, 18, 27, 36 and 45. Note We can also write the Table' of required number to get the multiples of that number.
