#2**+2 **

1)

Multiply 10 by f and bring it into the numerator. The expression is now \(\frac{6+10f}{f}=\frac{2(3+5f)}{f}\)

2)

Multiply 5a by b, add to numerator: \(\frac{5ab+2a}{b}\)

An alternate way of writing that: \(\frac{a(5b+2)}{b}\)

(Since both terms in the numerator have the letter a, you can divide each by a, and place them in parenthesis, then multiply the sum by a.)

@Melody: Was that a sufficient explanation?
