Let us assume that the number of strips she able to make be x .
As given
Emma is scrapbooking she has 9 inches of paper .
\(needs\ to\ cut\ into\ \frac{2}{5}\ inch\ stripes\ of\ paper.\)
Than the equation is become in the form

solving
\(x =\frac{9\times5}{2}\)
x = 22.5
Therefore the number of strips Emma will able to make be 22 .
Hence proved
