You have:
You can follow the next general formula to diide fractions:
Then you get:
You multiply:
[tex]\frac{-3\cdot16}{8\cdot15}=-\frac{48}{120}[/tex]You can simplify by dividing the numerator and denominator by the same number:
You can strat dividing both numbers into 2 as they are even numbers:
[tex]-\frac{48}{120}=-\frac{24}{60}=-\frac{12}{30}=-\frac{6}{15}[/tex]Then you can divide the -6 and 15 into 3
[tex]-\frac{6}{15}=-\frac{2}{5}[/tex]Then the final answer is:[tex]-\frac{2}{5}[/tex]
