Question

identify the value of x that makes each pair of ratios equivalentx:4 and 45:20A) 8B) 9C) 10

Answer 1

In order to find the value of x to make equivalent ratios, let's compare the ratios in their fraction form:

$\frac{x}{4}=\frac{45}{20}$

Now, solving this equation for x, we have:

$\begin{gathered} 20\cdot x=4\cdot45 \\ 20x=180 \\ x=\frac{180}{20} \\ x=9 \end{gathered}$

So the value of x is 9, therefore the correct option is B)
