Question

using divisibility tests, determine which of following numbers are divisible by 6:
297144 (b) 1258 (c) 4335 (d) 61233 (e) 901352
438750 (g) 1790184 (h) 12583 (i) 639210 (j) 17852​

Answer 1

Step-by-step explanation:

A number is divisible by 6 if its divisible by 2 and 3. That is the divisibility rule for 6.

In oder to see which numbers are divisible by 3, add all the digits of the number,

For eg, if we wanna see weather or not 297144 is divisible by 3, add the digits: 2+9+7+1+4+4 we get answer as 27

Now add the digits of 27, 2+7 = 9

We stop adding digits when we get a one-digit number, if the one digit number is divisible by 3, then the whole number that u started with is divisible by 3, so, becuz 9 is divisible by 3, 297144 is divisible by 3.

For 2, all even numbers are divisible by 2

Once u find weather or not the numbers are divisible by 2 and 3, th enumbers divisible by both 2 and 3 are divisble by 6
