Question 890542
The rational expression 7x2y3/3rs represents the area of the rectangle, and 3xy/r represents the length. What rational expression represents the width?
:
We can find the width by dividing the area by the length
{{{((7x^2y^3))/((3rs))}}}
-----------
{{{((3xy))/r}}}
Invert the dividing fraction and multiply
{{{((7x^2y^3))/((3rs))}}} * {{{r/((3xy))}}}
cancel, r and xy
{{{((7xy^2))/((3s))}}} * {{{1/((3))}}} = {{{((7xy^2))/((9s))}}}
