Use the Cross Products Property to solve the proportion 5/n =16/32

vaieri [72.5K]

Answer:

$x = 10$

Step-by-step explanation:

If we have our proportion set up like this:

$\frac{5}{n} = \frac{16}{32}$

Then using the cross products property, we can find the value of n.

The property states that the two numbers that are diagonal to each other DIVIDED by the number diagonal to the variable will equal the variable.

So:

$32\cdot5 = 160\\160\div16 = 10$

Hope this helped!
