Q:

What is 3 3/4*(-1 1/2)?

Accepted Solution

A:
Answer: [tex]-\frac{45}{8}[/tex] or [tex]-5\ \frac{5}{8}[/tex]Step-by-step explanation: Rewrite each mixed numbers as fractions: [tex]3\ \frac{3}{4}=\frac{(4*3)+3}{4}=\frac{12+3}{4}=\frac{15}{4}\\\\1\  \frac{1}{2}=\frac{(2*1)+1}{2}=\frac{3}{2}[/tex] Make the multiplication: Multiply the numerator of the first fraction by the numerator of the second fraction and  the denominator of the first fraction by the denominator of the second fraction. [tex](\frac{15}{4})(-\frac{3}{2})=-\frac{45}{8}[/tex] or [tex]-5\ \frac{5}{8}[/tex]
