Finding the Smallest Number
To solve this question, we need to find the smallest number among the given options. Let's compare each of the fractions and the decimal.
(A) \( \frac{5}{7} \)
This is a simple fraction that cannot be simplified further.
(B) \( \frac{24}{5} \)
This is an improper fraction, meaning that it is greater than 1.
(C) \( 64 \)
This is an integer and it is obviously greater than 1.
(D) \( 2.37 \)
This is a decimal that is slightly bigger than 2 but less than 3.
Out of the given options, we're looking for the smallest. Fraction (A) \( \frac{5}{7} \) is less than 1, fraction (B) is more than 4 (since 20/5=4 and there is a remainder), the integer (C) is 64, and the decimal (D) is slightly bigger than 2.
Hence, the smallest number is (A) \( \frac{5}{7} \), because it's the only option less than 1.
