Can you guys help me? :-(

Answer:

$\frac{9}{10}$

Step-by-step explanation:

Find the LCD because like last time, you cannot add or subtract fractions with different denominators.

LCD = 10

Since the second fractions stayed at the same denominator, you will only have to multiply the first fraction.

$\frac{2 * 2}{5 * 2}$

$\frac{4}{10}$

$\frac{4 + 5}{10}$

$= \frac{9}{10}$
