Answer 1

Answer:

9

Step-by-step explanation:

$\frac{8}{12}=\frac{6}{a}$

$\frac{2}{3}=\frac{6}{a}$

$2a=6\cdot{3}$

$2a=18$

$a=\frac{18}{2}$

$a=9$

Answer 2

Answer:

a = 9

Step-by-step explanation:

So in this case you just cross multiply

8 : 12 = 6 :  a

6(12) = 8(a)

72 = 8a

Divide both sides by 8

a = 9
