Step-by-step explanation: To find the first 15 multiples of 8, we can multiply 8 by the first 15 whole numbers.
0 x 8 = 0
1 x 8 = 8
2 x 8 = 16
3 x 8 = 24
4 x 8 = 32
5 x 8 = 40
6 x 8 = 48
7 x 8 = 56
8 x 8 = 64
9 x 8 = 72
10 x 8 = 80
11 x 8 = 88
12 x 8 = 96
13 x 8 = 104
14 x 8 = 112
15 x 8 = 120
Therefore, the first 15 multiples of 8 are 0,8,16,24,32,40,48,56,64,72,80,88,96,104,112,120.
