Question 459469
Simplify and reduce the expression to lowest terms.
{{{(25r)/(10r+3)}}} - {{{(15r-3)/(10r+3)}}}
They have the same denominators so we can write it:
{{{(25r-(15r-3))/(10r+3)}}}
When we remove the bracket it changes the signs because of the neg
{{{(25r-15r+3)/(10r+3)}}} = {{{(10r+3)/(10r+3)}}} = 1; (When denominator=numerator it's always one)
