7/30+9/20 what is the answer pls hurry im so confused

Svetradugi [14.3K]

Here is your answer:

$\frac{7}{30} + \frac{9}{20}$
Find common denominator:
$30 \times 20 = 60 /20 \times 30 = 60$
Common denominator is 60:
$\frac{7}{30} + \frac{9}{20} = \frac{140}{60} + \frac{270}{60}$
$140 + 270 = 410$
$= \frac{410}{60}$
$\frac{410}{60} \div 2 = \frac{205}{30} \div 5 = \frac{41}{6}$
= $\frac{41}{6} or 6\frac{5}{6}$

Hope this helps!
