Answer:

[tex]\frac{9}{10}[/tex]

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.

[tex]\frac{2 * 2}{5 * 2}[/tex]

[tex]\frac{4}{10}[/tex]

[tex]\frac{4 + 5}{10}[/tex]

[tex]= \frac{9}{10}[/tex]

Answer:

2/5 + 5/10 = 9/10

Step-by-step explanation:

Turn 2/5 into 4/10 to make the two fractions' denominators the same by multiplying 2 × 2 =4 and 5 × 2 = 10. Then add 4/10 + 5/10 to get 9/10.
