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

Answer

Answer 

Whole numbers that will be circled are 6, 14, 18, 32 and 50

 

Rule

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