Answer:
2/3
Step-by-step explanation:
You'll want both expressions to have the same denominator.
Let's make 2/5 into something divided by 15. Since 3*5 will give us 15, we'll multiply both 2 and 5 with 3.
[tex]\frac{2}{5} =\frac{2*3}{5*3} =\frac{6}{15}[/tex]
Now we can easily add the 2 expressions.
[tex]\frac{6}{15} + \frac{4}{15} =\frac{10}{15}[/tex]
Now, let's divide both 10 and 15 with 5 to simplify the expression.
[tex]\frac{10}{15} =\frac{10/5}{15/5} = \frac{2}{3}[/tex]
