What is 1/12 as a percentage?

Question

Twelfths show up whenever you split a year into months. Solve in your head. What is 	frac{1}{12} as a percentage? Aim: under 10 seconds.

Accepted Answer

A twelfth is half of a sixth. Since 	frac16 = 16.\overline{6}\%, 	frac{1}{12} = 	frac12 	imes 16.\overline{6}\% = 8.\overline{3}\%. So one month is about 8.33\% of a year. Takeaway. Chain off fractions you already know: a twelfth is a sixth halved, a twenty-fourth is a twelfth halved, and so on. The repeating 8.\overline3\% is worth memorising because monthly-to-annual conversions lean on it constantly.
