To determine which fractions are equivalent to 9/8, we need to find fractions with the same value.
Starting with 9/8, let's simplify the fraction:
9/8 ÷ 1/8 = 9.
We can see that this equals 9, so any fraction with a numerator of 9 and a denominator of 8 is equivalent to 9/8, as long as the numerator and denominator are not both divisible by any common factors.
Let's analyze our options:
3/4: The numerator and denominator can both be divided by 1, so the fraction can be simplified to 3/4 ÷ 1/4 = 3.
5/4: The numerator and denominator can both be divided by 1, so the fraction can be simplified to 5/4 ÷ 1/4 = 5.
18/16: The numerator and denominator can both be divided by 2, so the fraction can be simplified to 9/8 ÷ 8/8 = 9/8. This fraction is equivalent to 9/8.
16/18: The numerator and denominator have a common factor of 2, so this fraction can be simplified to 8/9. This fraction is not equivalent to 9/8.
27/24: The numerator and denominator can both be divided by 3, so the fraction can be simplified to 9/8 ÷ 8/8 = 9/8. This fraction is equivalent to 9/8.
In conclusion, the fractions that are equivalent to 9/8 are 3/4, 5/4, 18/16, and 27/24.
