Help with this problem please !!!!!

Answer 1

Answer:

The answer is k = 28

Step-by-step explanation:

$\frac{12}{k}=\frac{18}{42}$

Cross multiply. Remember, $\frac{a}{b}=\frac{c}{d}$ ⇒ ad=bc

$\frac{12}{k}=\frac{18}{42}$ ⇒ k·18=12·42

k·18=12·42

Simplify

18k=504

÷18 on both sides

k=504÷18

Simplify

k=28

Answer 2

Answer:

28

Step-by-step explanation:

Cross multiply

18k = 12 x 42

18 k = 504

   k = 504/18

   k = 28
