Question

Which is smaller: 5 nanometers or 50 micrometers

Answer 1

5 nanometers is smaller

Answer 2

recall that the larger the denominator, the smaller the fraction.

$\bf \stackrel{~\hfill micro~~}{10^{-6}\implies \cfrac{1}{10^6}\implies \cfrac{1}{1000000}}~~>~~10^{-9}\implies \cfrac{1}{10^9}\implies \stackrel{nano}{\cfrac{1}{1000000000}}$
