There are 52 weeks in a year. Ben has lived in london for two fifths of year. How many weeks has ben lived in london?
masha68 [24]

Answer:

\frac{104}{5} weeks or 20\frac{4}{5} weeks

Step-by-step explanation:

To do this we can set up a proportion

\frac{52}{1} *\frac{2}{5}

This will tell us how many weeks are in 2/5 of a year

Let's evaluate this

\frac{104}{5}

We cannot simplifiy this anymore, so we will leave it as an improper fraction, or a mixed number as shown below

20\frac{4}{5} weeks
