Answer:

simplified :
Explanation:
first, we turn them into improper fractions

First, we multiply 3×4=12+3=15 the demoninator will remain the same.
2×8=16+5=21, denominator remains the same.

when it comes to division with fractions, you flip the right(direction)fraction then multiply.

15×8=120
4×21=84

then turn in back into a mixed fraction.

demoninator remains the same, how many times 84 goes into 120, which is once(whole number) and how many is left over (numberator)
