Answer:

Step-by-step explanation:

As the fractions are not like fraction, find LCM for 5 and 15

5 is a prime number and 15 is multiple of 5.So, LCM = 15

$\dfrac{3}{5}=\dfrac{3*3}{5*3}=\dfrac{9}{15}\\\\\dfrac{7}{15}+\dfrac{3}{5}=\dfrac{7}{15}+\dfrac{9}{15}$

$= \dfrac{7+9}{15}\\\\=\dfrac{16}{15}\\\\= 1\dfrac{1}{15}$

Answer:

Step-by-step explanation:

7/15 + 3/5

I'd multiply 3/5 by 3 so that both of the denominators (bottom number) are the same.

Now all we have to do is add the Numerators tog

7/15 + 9/15ether (the top number)

7/15 +9/15 = 16/15 or 1 1/15
