2 Find the Least Common Denominator (LCD) of / frac{5}{6},/frac{3}{4}

6



5

,

4



3

. In other words, find the Least Common Multiple (LCM) of 6,46,4.

LCD = 1212

3 Make the denominators the same as the LCD.

/frac{5/times 2}{6/times 2}+/frac{3/times 3}{4/times 3}

6*2



5*2

+

4*3



3*3



4 Simplify. Denominators are now the same.

/frac{10}{12}+/frac{9}{12}

12



10

+

12



9



5 Join the denominators.

/frac{10+9}{12}

12



10+9



6 Simplify.

/frac{19}{12}

12



19



7 Convert to mixed fraction.

1/frac{7}{12}1
