Question 996229


{{{ A= B/C}}}...here you have whole number {{{A}}} on the left side and fraction {{{B/C}}} on the right side of equation sign
recall that whole number {{{A}}} could be written as a fraction like this: {{{A/1}}}

so you have {{{ A/1= B/C}}}...now you can cross multiply

{{{ A*C= B*1}}} so, you have

{{{ A*C= B}}}, now both sides divide by {{{A}}}

 {{{ A*C/A= B/A}}}...simplify

{{{ cross(A)*C/cross(A)= B/A}}}

{{{ C= B/A}}}
