Question 67595
if (3/4-2/3)+(1/2+1/3)is calculated and the answer reduced to simplest terms, what is the denominator of the resulting fraction?
The lowest common denominator of all the fractions is 12 because the lowest number that 2,3, and 4 all divide evenly into 12.
Whatever you do to the denominator to get 12, you also have to do to the numerator.
{{{(3*3/(4*3)-2*4/(3*4))+(1*6/(2*6)+1*4/(3*4))}}}
{{{(9/12-8/12)+(6/12+4/12)}}}
{{{(9-8)/12+(6+4)/12}}}
{{{1/12+10/12}}}
{{{(1+10)/12}}}
{{{11/12}}}
{{{11/highlight(12)}}}
The denominator is 12.
Happy Calculating!!!
