Question 65233
Evaluate the expression when x=5/6 & y= - 3/10
x-y
{{{5/6-(-3/10)}}}
{{{5/6+3/10}}}  The LCD is 30, because that's the lowest number that both 6 and 10 go into evenly.
{{{5*5/(6*5)+3*3/(10*3)}}}
{{{25/30+9/30}}}
{{{(25+9)/30}}}
{{{34/30}}}  This is reducable by 2.
{{{17*2/(15*2)}}}
{{{17/15}}}  If you're not allowed improper fractions:
1 2/15
