Question

2/n+1=9/6

solve each proportion

Answer 1

n = 1/3

Explanation:

2/n + 1 = 9/6

2 * 6 = ( n + 1 ) * 9

12 = ( n + 1 ) * 9

( n + 1 ) * 9 = 12

( n + 1) / 9

12 / 9

n + 1 = 4/3

n + 1 - 1 = 4/3 -1

n = 1/3

Answer 2

n =1/3

Explanation:

2/(n+1)=9/6

Using cross products

2 * 6 = 9 * (n+1)

12 = 9( n+1)

Distribute

12 = 9n+9

Subtract 9 from each side

12 -9 = 9n+9-9

3 = 9n

Divide each side by 9

3/9 = 9n/9

1/3 =n
