Question 940930

let the number of alligators be {{{x}}}
if {{{3/8}}} of the alligators are female if there are {{{15}}} male, then

{{{x=(3/8)x+15}}}.....solve for {{{x}}}

{{{x-(3/8)x=15}}}

{{{8x/8-(3/8)x=15}}}

{{{5x/8=15}}}

{{{5x=15*8}}}

{{{x=(15*8)/5}}}

{{{x=(cross(15)3*8)/cross(5)1}}}

{{{x=3*8}}}

{{{x=24}}}=> total number of alligators there

{{{24-15=9}}}=> total number of female alligators

{{{15-9=6}}}=> there are {{{6}}} more males than females
