Equivalent fraction with denominator 18

Equivalent to what?

To find an equivalent fraction with a denominator of 18, you need to multiply both the numerator and the denominator of the given fraction by the same nonzero whole number. Here's how you can do it:

Let's say you have a fraction with a different denominator, such as 5/7. To change the denominator to 18, you need to find a number that you can multiply both 7 and 18 by to get a common multiple. In this case, you can multiply 7 by 2 and 18 by 2, resulting in 14/36.

However, it's important to simplify the fraction to its lowest terms. To simplify, you need to find the greatest common divisor (GCD) of 14 and 36, which is 2. Divide both the numerator and the denominator by 2, and you will get the final equivalent fraction: 7/18.

So, starting with a fraction like 5/7, multiplying both the numerator and denominator by 2 will give you the equivalent fraction 7/18.
