Solve each proportion:
\(\frac{3.2}{9} = \frac{n}{36}\)
Find \(n\).
Answer (3)
9 3.2 = 36 n
Now cross-multiply.
115.2 = 9 n
Solve for n .
9 115.2 = 9 9 n n = 12.8
To solve the proportion 3.2/9 = n/36, we can cross-multiply to find the value of n. This means we multiply 3.2 by 36 and then divide the result by 9 to find n.
Here's the step-by-step process:
Multiply 3.2 by 36, which gives us 115.2.
Next, divide 115.2 by 9.
The result is the value of n, which is 12.8.
So, the solution to the proportion is n = 12.8.
To find n in the proportion 9 3.2 = 36 n , we cross-multiply to get 3.2 × 36 = 9 n , leading to n = 12.8 .
