Answer:

[tex] \frac{13}{20} [/tex]

Step-by-step explanation:

[tex] \frac{1}{4} + \frac{2}{5} [/tex]

First, we need to make the demoninators the same so we times 4 by 5 and whatever we do to the bottom, we do to the top, and 5 by 4.

[tex] \frac{ 1 \times 5}{4 \times 5} + \frac{2 \times 4}{5 \times 4} [/tex]

[tex] \frac{5}{20} + \frac{8}{20} [/tex]

[tex] = \frac{13}{20} [/tex]

demoninator now doesn't change unless you're multiplying or dividing.
