You can't add improper fractions (?)
And if you're adding fractions, the denominators should be the same.. if not, you should find it's LCM <least common multiple> (im not 100% sure if it is LCM or GCF lels)
the lcm of 16 and 10 is 80.. so 80÷16= 5 , 5×10= 50
80÷10=8 , 8×3= 24.. so 50/80 + 24/80= 74/80
if you'll lowest term it, it's 37/40 XDD
