Answer:


Step-by-step explanation:

Those are fractions, are they not? I'll treat them that way.

[tex]\dfrac{2}{5}+\dfrac{2}{3}[/tex]

Find the lowest common denominator.

You need 1 three and 1 five.

2/5 = (2*3)/(5 * 3) = 6 / 15

2/3 = (2*5)/(3*5) = 10 /15

[tex]\dfrac{2}{5}+ \dfrac{2}{3}=[/tex] [tex]\dfrac{6}{15}+\dfrac{10}{15}[/tex]

[tex]\dfrac{2}{5}+ \dfrac{2}{3}=\dfrac{16}{15}[/tex]   Just add the numerators.

It is reduced. There are other ways to write it

16/15 = 1 1/15 is one of them
