Write each percent as a fraction. Give answers in lowest terms.
47%47\%

검증된 단계별 안내
1
Recall that a percent means 'per hundred,' so 47% can be written as the fraction \( \frac{47}{100} \).
Write the fraction explicitly: \( \frac{47}{100} \).
Check if the numerator and denominator have any common factors other than 1 to simplify the fraction.
Since 47 is a prime number and does not share any common factors with 100, the fraction \( \frac{47}{100} \) is already in its lowest terms.
Therefore, the fraction form of 47% in lowest terms is \( \frac{47}{100} \).

Simplifying Fractions

Simplifying fractions means reducing them to their lowest terms by dividing numerator and denominator by their greatest common divisor (GCD). For 47/100, since 47 is prime and does not divide evenly into 100, the fraction is already in simplest form.
