Ken grew 4/5 of an inch last year. Dang grew 3/8 of an inch. Who grew more and by how much?

Alex73 [517]

So, first things first, you need to get a common denominator for the two fractions.

That would be 40.
$\frac{4}{5} \times \frac{8}{8} = \frac{32}{40}$
$\frac{3}{8} \times \frac{5}{5} = \frac{15}{40}$

Which one is larger?
By how much is it larger?
Remember to reduce.
