Answer 1

Answer:

B

Step-by-step explanation:

3 + f = 14 $\frac{2}{7}$ ← change to improper fraction

3 + f = $\frac{100}{7}$ ( multiply through by 7 to clear the fraction )

21 + 7f = 100 ( subtract 21 from both sides )

7f = 79 ( divide both sides by 7 )

f = $\frac{79}{7}$ = 11 $\frac{2}{7}$ → B

Answer 2

Answer:

B. $f=11\frac{2}{7}$

Step-by-step explanation:

We have the equation 3 + f = 14 2/7

We need to get f alone, doing so is subtracting three from both sides:

3 + f = 14 2/7

-3     = -3

14 2/7 - 3 = [11 2/7]

Leaving us with f = 11 2/7

This is B.
