# Divisibility by 2 Circle each whole number that is evenly divisible by 2.  Write a rule that tells you when a whole number is evenly divisible by 2. ______________________________

### Explanation

Solution

= A whole number is a set of numbers that include 0,1,2,3,..........upto infinity

= A number evenly divisible by 2 means that remainder is 0 when the number is divided by 2

Rule

If a whole number ended with 0,2,4,6 or 8, then the number is evenly divisible by 2.

a.) 6

= 6 is a whole number that ends with 6 also

Therefore, according to rule, it is evenly divisible by 2

b.) 13

= 13 is a whole number that ends with 3

Therefore, according to rule, it is not evenly divisible by 2

c.) 14

= 14 is a whole number that ends with 4

Therefore, according to rule, it is evenly divisible by 2

d.) 18

= 18 is a whole number that ends with 8

Therefore, according to rule, it is evenly divisible by 2

e.) 25

= 25 is a whole number that ends with 5

Therefore, according to rule, it is not evenly divisible by 2

f.) 32

= 32 is a whole number that ends with 2

Therefore, according to rule, it is evenly divisible by 2

g.) 50

= 50 is a whole number that ends with 0

Therefore, according to rule, it is evenly divisible by 2

h.) 77

= 77 is a whole number that ends with 7

Therefore, according to rule, it is not evenly divisible by 2
