Answer:
[tex]-2\frac{6}{25}[/tex]
Step-by-step explanation:
If the total weight change was [tex]-11 \frac{1}{5}lb[/tex] in 5 months, then the average would be the quotient between these two quantities, that is
[tex]-11 \frac{1}{5}lb \div 5[/tex]
However, we need to transform the mixed number into a fraction. We do that by multiplying -11 by 5 and summing the reminder of 1, so the expression would be
[tex]-\frac{56}{5}lb \div 5[/tex]
Now,we divide
[tex]-\frac{56}{5}lb \times \frac{1}{5}=-\frac{56}{25}=-2\frac{6}{25}[/tex]
Therefore, the average weight change is
[tex]-2\frac{6}{25}[/tex]
