Answer:
-77.625
Step-by-step explanation:
I'm assuming you meant (6 3/4)(-11.5). If that's the case, then:
Convert 6 3/4 into a mixed number with decimal fraction: 6.75.
Then multiply this 6.75 by (-11.5). Using a calculator, we get:
-77.625
The value of the expression is -77 5/8
In order to determine the value of the expression, we are to multiply[tex]6\frac{3}{4} by -11.5[/tex]
In order to do this, we are to convert the mixed fraction and the decimal to improper fractions
To convert -11.5 to an improper fraction, -11.5 has to be converted to a mixed fraction first
Remember that 0.5 = [tex]\frac{1}{2}[/tex]
The decimal now becomes [tex]-11\frac{1}{5}[/tex]
When converted to an improper fraction, [tex]6\frac{3}{4} becomes \frac{27}{4}[/tex] and [tex]-11\frac{1}{2} becomes -\frac{23}{2}[/tex]
[tex]\frac{27}{4}[/tex] x [tex]-\frac{23}{2}[/tex] = [tex]-\frac{621}{8}[/tex]
converting to mixed fraction, the number becomes -77 5/8
