Question

If a 3-digit number 5x2 is divisible by 3, find the sinallest value of x.
​

Answer 1

Answer:

For a number to be divisible by 3, its sum has to be divisible by 3.

here,

5x2=7x

we get the number 7 that is not divisible by 3, so we need to add 2 to it to make the number divisible by 3.

hence, x=2

5+2+2=9

which is divisible by 3, hence the number 522 is divisible by 3.

U can put any value like 5,8 etc

but here they asked for the smallest value, so we took 2

I hope this helped U!!!

Answer 2

Answer:

if 5x2 is divisible by 3

and the divisibility of 3 is sum of all the digits

so

Step-by-step explanation:

5+x+2=multiple of 3
