Question

Write the natural numbers from \(102\) to \(113\). What fraction of them are prime numbers?

Answer 1

Natural numbers from \(102\) to \(113\): \(102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113\) 
Prime numbers from \(102\) to \(113\): \(103, 107, 109, 113\) 
Hence fraction of prime numbers = \(\frac{4 }{12} =\frac{1}{3}\)
