4. Are these numbers divisible by 2? A.458 B.1,279 C.759 D.555 E.1,050

5. Add up the digits of the number If that number is divisible by 3, then the original number is too

6. For example, take the number 738 Add up the digits of the number 7 + 3 + 8 = 18 If that number is divisible by 3, then the original number is also Is 18 divisible by 3? If your sum is still a big number, continue to add the digits 1 + 8 = 9 Is 9 divisible by 3?

7. Are these numbers divisible by 3? A.639 B.56 C.86 D.360 E.468 - (add up digits: 6+3+9=18: since 18 is divisible by 3, so is the number.)

8. If the number ends in 0 or 5

9. Are these numbers divisible by 5? A.554 B.6,890 C.345 D.902 E.845

10. If the number is divisible by 2 and 3 it is divisible by 6 also

11. For example, take the number 738 Check if it’s divisible by 2: –Yes, since it’s even! Check if it’s divisible by 3: –Add up the digits of the number 7 + 3 + 8 = 18 –Yes, Since 18 is divisible by 3, so is the number! Since the number is divisible by 2 & 3 it’s also divisible by 6!!!
