F/13 = 6.2 what is the value of f
nekit [7.7K]

Answer:

The value of f is 80.6.

Step-by-step 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\frac{a}{26}=17.9

We can multiply both sides by 26 to get the a by itself so the equation can be solved.

\displaystyle26\times\frac{a}{26}=17.9\times26\\\\a = 465.4

Therefore, we can apply this same technique to the equation \frac{f}{13}=6.2.

\displaystyle\frac{f}{13}=6.2\\\\13\times\frac{f}{13}=6.2\times13\\\\f = 80.6\ \text{or} \ \frac{403}{5}

Therefore, the value of f is 80.6.
