Which pair of rational numbers lie between 1/5 and 2/5 -

a. 262/1000, 275/1000
b. 362/1000, 562/1000
c. 451/1000, 552/1000
d. 121/1000,131/1000

• a. 262/1000, 275/1000 is the answer.
  
  Explanation:
  Initial Value = 1/5 and 2/5
  So,
  (1*200)/(5*200)=200/1000 and (2*200)/(5*200)=400/1000.
  
  So the value lies between 200/1000 and 400/1000.
  
  As per that, the value is 262/1000, 275/1000

• given: 1/5, 2/5 which can be written as 0.2 and 0.4
  so answer should be between 0.2 and 0.4
  
  Since given options are with denominator 1000 the values can be directly written as,
  a. 0.262, 0.275
  b. 0.362, 0.562
  c. 0.451, 0.552
  d. 0.121, 0.131
  
  So directly it can be said as option 'a' is the answer

• 1/5=0.2
  2/5=0.4
  So answer must lie between these two numbers
  let's go for option verification
  a.)262/1000=2.62
  275/1000=2.75 these two lie between them So answer is a

• -->first find lcm of denominators
  lcm(5,5)=5
  so no change in the values they stilll remain 1/5 and 2/5
  as 0.2 and 0.4 then check out the vallues which lie between them
