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:

`(21)/(x)=(7)/(10)`

Now, solving this equation for x, we have:

`\begin{gathered} 7\cdot x=21\cdot10 \\ 7x=210 \\ x=(210)/(7) \\ x=30 \end{gathered}`

So the value of x is 30.
