What is two-fifths of one-half?

Answer 1

This is actually a simple math problem, let's take it apart word for word.

two-fifths = 2/5

of = x (times)

one-half = 1/2

A fraction is actually just an expression of a simple division problem, so we can approach this one of two ways:

2/5 = 0.4 and 1/2= 0.5

0.4 x 0.5 = 0.2

Or we can leave the fractions as are and multiply straight across:

2 1 2

-- x -- = --

5 2 10

Which can be simplified (you have to divide the top and bottom by the SAME number)

So, 2/2 over 10/2 = 1/5

To double check, divide 1 by 5 and look at your top answer...both are 0.2
