Ratio conversion and proportion problem.


Let M be the mass in grams you are looking for.
{{{140*grams/(5*ounces)=M*grams/(2*pounds)}}}


Notice that the units do not match.  The dimensions match but the proportion is not yet ready to finish because matching units are needed.


We have this fact:  1 pound = 16 ounces.  We have two choices.


EITHER  
 {{{140*grams/((5*ounces)(1*pound)/(16*ounces))=M*grams/(2*pounds)}}}
OR
{{{140*grams/(5*ounces)=M*grams/((2*pounds)(16*ounces)/(1*pound))}}}
