Question

Write all the proper fraction s whose numerator and denominator are prime numbers between 65 and 80.

Answer 1

Answer:

Given Nos are 65 & 80

To write all proper fraction using only prime nos between given nos.

A Fraction is called Proper fraction if its numerator is smaller than denominator. for ex; $\frac{1}{2}\:,\:\frac{9}{100}\:,\:etc$

Prime no is a no which has only two factor .i.e., 1 and no itself. for ex: 2 , 3 , 5 , 7 , 11 , etc

Prime Nos between 60 and 80 = 61 , 67 , 71 , 73 , 79

Proper Fractions made from them are the following:

$\frac{61}{67}\:,\:\frac{61}{71}\:,\:\frac{61}{73}\:,\:\frac{61}{79}\:,\:\frac{67}{71}\:,\:\frac{67}{73}\:,\:\frac{67}{79}\:,\:\frac{71}{73}\:,\:\frac{71}{79}\:,\:\frac{73}{79}$
