First, you want to change your mixed number into a single fraction--you do that by multiplying 6 and 1, then adding 5 and setting it over your denominator.
1 5/6 becomes 11/6
now you just multiply your fractions straight across: 4 * 11 = 44 5 * 6 = 30
so your answer is 44/30, but you can simplify it into 22/15
but you said it was adding fractions, though it's a multiplication symbol, so in that case:
4/5 + 11/6 get your least common denominator, ill choose 30 24/30 + 55/30 79/30 is your answer
