$7 9/10$

Find the LCM (Least Common Multiple) on the denominator. Here, the LCM is $10$ . Then you have to divide $10$ by $5$ to change the first fraction.

$10 /5 = 2$

Next, multiply that by $3$ to get $6$ . Now you have the fractions

$2 6/10" "$ and $" "5 3/10$

Adding that, you add the numerators and copy the denominators. Then add the whole numbers. You get

$(2+5) ((6 + 3))/10 = 7 9/10$
