Write the ratio 15:3 as an equivalent ratio of 5:x

Answer 1

To find the equivalent ratio of 15:3 in the form of 5:x, we can set up the equation based on the relationship between the ratios.

Given: \[ \frac{15}{3} = \frac{5}{x} \]

We can simplify the left side: \[ \frac{15}{3} = 5 \]

Now we have: \[ 5 = \frac{5}{x} \]

To solve for \(x\), we can cross-multiply: \[ 5x = 5 \]

Dividing both sides by 5 gives: \[ x = 1 \]

Thus, the ratio \(5:x\) is: \[ 5:1 \]

So, the equivalent ratio of 15:3 in the form of 5:x is 5:1.
