Answer:
There are infinitely many fractions that are equivalent to a given fraction with a denominator of 45.
Explanation:
To determine equivalent fractions with a denominator of 45, we can multiply or divide the numerator and denominator of a fraction by the same number. Here are some examples:
1/5 = 9/45 (multiply numerator and denominator by 9)
2/9 = 10/45 (multiply numerator and denominator by 5)
3/8 = 16/45 (multiply numerator and denominator by 5, then by 2)
4/15 = 12/45 (multiply numerator and denominator by 3)
5/18 = 12/45 (multiply numerator and denominator by 2.5, which is the same as multiplying numerator by 5 and denominator by 2)
So, there are infinitely many fractions that are equivalent to a given fraction with a denominator of 45.
