Question 18 Find the sum in reduced form. 2 5 + 2 3

Answer 1

Answer:

Step-by-step explanation:

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

$\dfrac{2}{5}+\dfrac{2}{3}$

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

$\dfrac{2}{5}+ \dfrac{2}{3}=$ $\dfrac{6}{15}+\dfrac{10}{15}$

$\dfrac{2}{5}+ \dfrac{2}{3}=\dfrac{16}{15}$   Just add the numerators.

It is reduced. There are other ways to write it

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