Question

Add. Write each answer in lowest term.13/15+7/10+2/5​

Answer 1

$\frac{13}{15}+\frac{7}{10}+\frac{2}{5\\}$

Taking LCM of denominators 15,10 and 5

 2| 15,10,5

 3| 15,5,5

 5|  5,5,5

   |   1,1,1

LCM= 2×3×5

       = 30

Converting unlike fraction to like fractions

 $\frac{13}{15} * \frac{2}{2}= \frac{26}{30}$

 $\frac{7}{10}*\frac{3}{3} =\frac{21}{30}$

  $\frac{2}{5}*\frac{6}{6}=\frac{12}{30}$

Adding fractions

$\frac{26}{30} +\frac{21}{30} +\frac{12}{30} =\frac{59}{30}$

Converting into mixed fraction

$1\frac{29}{30}$
