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.
