Question

Identify the value of x that makes each pair of ratios equivalent 21 to x and 7 to 10

Answer 1

In order to find the value of x to make the ratios equivalent, we can compare them in their fraction form:

$\frac{21}{x}=\frac{7}{10}$

Now, solving this equation for x, we have:

$\begin{gathered} 7\cdot x=21\cdot10 \\ 7x=210 \\ x=\frac{210}{7} \\ x=30 \end{gathered}$

So the value of x is 30.
