Given Between 3/5 and 4/5 there can be ___ rational numbers

  • There exists infinite number of rational numbers between any two rational numbers.
  • We need to find the rational numbers between 3/5 and 4/5. So let it be 5.
  • So first multiply both numerator and denominator by 5 + 1 = 6 we get
  • So 3/5 x 6 / 6 = 18/30 and 4/5 x 6/6 = 24 /30
  • Now we can write the fractions between 18/30 and 24/30 as  
  • So 119/30, 20/30, 21/30, 22/30, 23/30
  • Given The sum of two negative whole numbers is always:
  • We need to find the sum of two negative whole numbers is always negative.
  • Consider a few examples like – 5 + - 6 = - 11 and -4 + - 3 = - 7 Similarly for sum of  all negative numbers it will be negative. So there is a rule
  •  So + x + = +
  •      + x - = -
  •  So – x - = -
  •   So – x + = -
