Question 367875
Convert the mixed numbers to fractions,
{{{12+2/3=36/3+2/3=38/3}}}
{{{5+1/4=20/4+1/4=21/4}}}
{{{6+1/2=12/2+1/2=13/2}}}
Use a common denominator, {{{12}}}.
{{{(38/3)(4/4)=152/12}}}
{{{(21/4)(3/3)=63/12}}}
{{{(13/2)(6/6)=78/12}}}
Now substitute,
{{{50-(12+2/3)-2(5+1/4)-2(6+1/2)=50-(152/12)-2(63/12)-2(78/12)}}}
{{{50-(12+2/3)-2(5+1/4)-2(6+1/2)=600/12-(152/12)-(126/12)-(156/12)}}}
{{{50-(12+2/3)-2(5+1/4)-2(6+1/2)=(600-152-126-156)/12)}}}
{{{50-(12+2/3)-2(5+1/4)-2(6+1/2)=(166)/12)}}}
{{{50-(12+2/3)-2(5+1/4)-2(6+1/2)=(83)/6)}}}
{{{highlight(50-(12+2/3)-2(5+1/4)-2(6+1/2)=13+5/6)))}}}
