What fractions are less than one-half.explain?

Answer 1

Any fraction with numerator = 1 and denominator > 2.

Suppose numerator = 1 and denominator = n where n > 2

then 1/2 - 1/n = n/(2n) - 2/(2n) = (n-2)/(2n)

Since n>2 the numerator of the above answer is positive nad the denominator (= 2n) is also positive so the difference between the two fractoins is positive.

That is, 1/2 > 1/n or, equivalently, 1/n is less than 1/2.
