What number could replace n?
6/12 = 2/n
n = ___

n = 4

Since you divide 6 by 3 to get 2, you divide 12 by 3 and you get 4.

4

Step-by-step explanation: This problem is already set out as a proportion. you can cross multiply 6 times n which gives you 6n. Then 12 times 2 which gives 24.

Now you have 6n = 24. You can divide right away, or think of a number when you multiply into 6 gives you 24. Its obvious the answer is 4 because 6 x 4 = 24.

Check:

6/12 = 1/2

2/4 = 1/2
