The answer is 210 because you do the checkmark approach on 12 1/2 and you get 25 over 2 and when you do the checkmark approach on 17 1/5 is it 86 over 5 then you multiply the two fractions and you get 2150÷10 and then you get your answer to 210!

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23

Leto [7]

Given :

All the natural numbers below 1000 that are multiples of 3 or 5 .

To Find :

The sum of all the multiples of 3 or 5 below 1000.

Solution :

Max multiple of 3 is 999 .

Max multiple of 5 id 995 .

So , number of multiple of 3 is :

$999=a+(n-1)d\\\\999=3+3(n-1)\\\\n=333$

Similarly for 5 .

$995=a+(n-1)d\\\\995=5+5(n-1)\\\\n=199$

Now , sum of all multiple of 3 is given by :

$S_3=\dfrac{n}{2}(2a+(n-1)d)\\\\S_3=\dfrac{333\times (2\times 3+332\times 3)}{2}\\\\S_3=166833$

Also , sum of all multiple of 5 is :

$S_5=\dfrac{n}{2}(2a+(n-1)d)\\\\S_5=\dfrac{199\times (2\times 5+198\times 5)}{2}\\\\S_5=99500$

Therefore , total sum :

$T=S_3+S_5\\\\T=166833+99500\\\\T=266333$

Now , there are some common number which we add two times like :

15 , 30 , 60 ......

So , we should subtract the sum of all multiple of 15 from T .

Now , sum of all multiple of 15 is 33165 .

So ,

$T=266333-33165\\\\T=233168$

Therefore , the sum of all the multiples of 3 or 5 below 1000 is 233168 .
