let the original number be {{{x}}}
if another number that is five times the original number, another number is {{{5x}}} 
if the product of a number and another number is {{{180}}}, we have

{{{x*5x=180}}}

{{{5x^2=180}}}

{{{x^2=180/5}}}

{{{x^2=36}}}

{{{x=sqrt(36)}}}

solutions:
{{{x=6}}} or {{{x=-6}}}
