Answer:

a) 8

b) 5

c) 12

Step-by-step explanation:

No. of multiples of x in a range (1,n) is n/x

a) So, No. of multiples of 3=25/3=8.33

We ignore the decimal part and the iteger is our answer.

Thus, there are 8 mutiples of 3.

b) No. of multiples of 5=25/5=5

Thus, there are 5 multiples of 5.

c) The total would be 5+8, which is 13.

But we should remember that 15 is a common multiple of both 5 & 3.

Thus we subtract the total no. of common multiples, which in this case is only 1.

So, the final answer would be 13-1=12 multiples.
