A.13
B.12
C.11
D.10

Answer 1

Answer:

B)12

Step-by-step explanation:

$\frac{16}{f}=\frac{12}{9}\\\\16*9=12*f\\\\\frac{16*9}{12}=f\\\\ 4*3=f\\\\f=12$

Answer 2

Answer: Option B

Step-by-step explanation:

16/f = 12/9

Multiply f on both sides

(16/f) × f = (12/9) × f

16 = (12/9) × f

Now, multiply 9 on both sides

16 × 9 = (12/9) × 9 × f

144 = 12 × f

Now, divide both sides by 12

144/12 = (12/12) × f

12 = f

f = 12
