Question 4
Write $2.75 \%$ as a fraction in simplest form.
Solution
Solution Steps
To convert a percentage to a fraction, we first express the percentage as a fraction with a denominator of 100. Then, we simplify the fraction by finding the greatest common divisor (GCD) of the numerator and the denominator and dividing both by this GCD.
Step 1: Convert Percentage to Fraction
To convert \(2.75\%\) to a fraction, we first express it as:
\[
\frac{2.75}{100}
\]
Step 2: Eliminate the Decimal
To eliminate the decimal, multiply both the numerator and the denominator by 100:
\[
\frac{2.75 \times 100}{100 \times 100} = \frac{275}{10000}
\]
Step 3: Simplify the Fraction
To simplify \(\frac{275}{10000}\), we find the greatest common divisor (GCD) of 275 and 10000, which is 25. We then divide both the numerator and the denominator by 25:
\[
\frac{275 \div 25}{10000 \div 25} = \frac{11}{400}
\]
