Question

5. Write the smallest digit and the greatest digit in the blank space of each of the following
numbers so that the number formed is divisible by 3:
(a) _ 6724 (b) 4765_2​

Answer 1

Answer:

(a) ___6724    

6+7+2+4= 19 

if we add 2 then the digit is divisible by 3  ( 19+2=21)

2 is the smallest digit 

26724 = 2 + 6 + 7 + 2 + 4 = 21

if we add 8 then the digit is divisible by 3  ( 19+8=27)

8 is the largest digit 

26724 = 8+ 6 + 7 + 2 + 4 = 36

b)  (b) 4765 ___2

4+7+6+5+2=24

if we add 0 then the digit is divisible by 3  ( 24+0=24)

0 is the smallest digit 

4765 ___2 = 4+ 7+6+5+0+2= 24

if we add 9 then the digit is divisible by 3  ( 24+9=33)

9 is the largest digit 

4765 ___2 =4+ 7+6+5+9+2= 33
