Answer:
[tex]-21\frac{1}{4}[/tex]
Step-by-step explanation:
First you need to get them into improper fractions. To do that multiply the whole number by the bottom number, and then add the top number:
[tex]-5\frac{2}{3} = -\frac{17}{3} \\3\frac{3}{4} = \frac{15}{4}[/tex]
Next, multiply the numerators (top numbers) by the denominators (bottom numbers)
[tex]-\frac{255}{12}[/tex]
Next just fix it and make it a mixed number. Just divide -255 by 12
The answer is -21.25
Just make that into a fraction and you are finished
