Question

Apply the means-extremes property to$\frac{x}{10}=\frac{4}{5}$and you get$5x=?$ and$x=?$

Short answer

The final answer is,

$5x=40$ and $x=8$.

Step-by-step solution

Step 1. Given information.

The given proportion is,

$\frac{x}{10}=\frac{4}{5}$

Step 2. Use mean extremes property. 

Product of means is equal to product of extremes,

So,

$5x=40$

Step 3. Now, dividing through-out by .

$\begin{array}{c}x=\frac{40}{5}\\ =8\end{array}$

Therefore, the final answer is$5x=40$, and$x=8$ .
