Question

What denominator for 21/3=49/ ?
would make these ratios proportional?(1 point)

Answer 1

To find the denominator that would make the ratios \( \frac{21}{3} \) and \( \frac{49}{x} \) proportional, we can set up the equation:

\[
\frac{21}{3} = \frac{49}{x}
\]

First, we can simplify \( \frac{21}{3} \):

\[
\frac{21}{3} = 7
\]

Now we have:

\[
7 = \frac{49}{x}
\]

Next, we can cross-multiply to solve for \( x \):

\[
7x = 49
\]

Now, divide both sides by 7:

\[
x = \frac{49}{7} = 7
\]

Therefore, the denominator that would make the ratios proportional is \( 7 \).
