Verified step by step guidance
1
Identify the given decimal and percent values: decimal is 0.05 and percent is 5%.
Recall that to convert a decimal to a fraction, write the decimal as the numerator with a denominator of a power of 10. For 0.05, write it as \(\frac{5}{100}\).
Simplify the fraction \(\frac{5}{100}\) by dividing both numerator and denominator by their greatest common divisor, which is 5, to get the fraction in lowest terms.
Verify the percent by remembering that percent means 'per hundred', so 5% is equivalent to \(\frac{5}{100}\), which matches the fraction before simplification.
Complete the table by writing the simplified fraction, the decimal 0.05, and the percent 5% as equivalent values.
