Using improper fractions, it is found that the percent of increase in the temperature of the solution was of 76.08%.
How to convert improper fractions to standard fractions?
The conversion is made according to the following formula:
[tex]a\frac{b}{c} = a + \frac{b}{c} = \frac{ac + b}{c}[/tex]
In this problem, the initial temperature was given by:
[tex]9\frac{4}{5} = 9 + \frac{4}{5} = 9.8[/tex]
The final temperature was given by:
[tex]17\frac{1}{4} = 17 + \frac{1}{4} = 17.25[/tex]
What is the percent change?
The percent change is given by the change divided by the initial temperature, and multiplied by 100%. Hence:
[tex]C = \frac{17.25 - 9.8}{9.8} \times 100\% = 76.02\%[/tex]
