Answer:
The value of f is 80.6.
Explanation:
We are given the equation and asked to solve for f.
If we are given a fraction with a variable in the numerator, we can multiply both sides of the equation by the denominator to isolate it.
For example, if you look at this equation:
![\displaystyle(a)/(26)=17.9](https://img.qammunity.org/2021/formulas/mathematics/high-school/e53xothhxp5ugolp5kon44bxv83lj2y490.png)
We can multiply both sides by 26 to get the a by itself so the equation can be solved.
![\displaystyle26*(a)/(26)=17.9*26\\\\a = 465.4](https://img.qammunity.org/2021/formulas/mathematics/high-school/kj28s7bpqnw5l45splwikv885kmwfo4c4l.png)
Therefore, we can apply this same technique to the equation
![(f)/(13)=6.2.](https://img.qammunity.org/2021/formulas/mathematics/high-school/izw7hlnks5mngneq787e0wmvh4i4zxkvwh.png)
![\displaystyle(f)/(13)=6.2\\\\13*(f)/(13)=6.2*13\\\\f = 80.6\ \text{or} \ (403)/(5)](https://img.qammunity.org/2021/formulas/mathematics/high-school/p042548n3rrso3nhee2rjvw6rjo7f2geft.png)
Therefore, the value of f is 80.6.
