by using decimals
72 reverse the digits divide by 3 = 24
Since there are 3 digits after the decimal, divide by 1000 (103):925 / 1000Then see if you can simplify.Since there are 3 digits after the decimal, divide by 1000 (103):925 / 1000Then see if you can simplify.Since there are 3 digits after the decimal, divide by 1000 (103):925 / 1000Then see if you can simplify.Since there are 3 digits after the decimal, divide by 1000 (103):925 / 1000Then see if you can simplify.
No it is not. To check - add all the digits together (in this case 2+6+9=17. If the sum of the digits can be divided exactly by 3, then the number itself will also divide by 3. In this case, 17 (the sum of the digits) does not divide exactly by 3.
No - because the sum of the digits does not divide exactly by 3.
to get an average you total the digits. 20+3+23=46 Then divide by the number of digits, in this case 3 46/3 = 15 1/3
Nope - since the sum of the digits don't divide by three.
No single digit determines divisibility by 3.
Yes it is... If you add the digits of ANY number together - and the result can be divided exactly by 3 or 9 - then the original number will also divide by 3 or 9. Since the digits of this number add together to make 18 - then 32643 will also divide by 3 or 9.
Nope... to check if a number will divide by 3 - add the digits of the number together. In this case, 6+7+7=20, which will not divide exactly by three.
Write the number and move the decimal point to the left 3 digits.
no because if u divide a number by three u will get a remainder
This is an easy one, if you know a little trick -> add up the digits ! 2 + 0 + 7 = 9. Is this divisible by 3 ? Yes ! then 207 is divisible by three. Divide it, you get 69. Add the digits = 15, also divisible by 3. Divide again, you get 23. So, 207 is divisible by 3 3 23.
