Question 60334
a package of ground beef weighs 1/2lb. A second package weighs 3/4lb. Together will there be enough to make 6 quater pound hamburgers? Explain how you know.
{{{1/2+3/4}}}lb
{{{2/4+3/4}}}lb
{{{(2+3)/4}}}lb
{{{5/4}}}lb
No, because we need {{{6(1/4)}}}lb={{{6/4}}}lb  
That means that we're 1/4 lb of hamburger short.
Happy Calculating!!!
