To express 70% as a fraction, follow these steps:
1. Understand the Concept of Percent: "Percent" literally means "per hundred." So, 70% means 70 per 100.
2. Write the Percentage as a Fraction: Start by writing 70% as a fraction with 100 as the denominator.
[tex]\[
\frac{70}{100}
\][/tex]
3. Simplify the Fraction: To simplify the fraction, find the greatest common divisor (GCD) of the numerator (70) and the denominator (100), and then divide both by this number. The GCD of 70 and 100 is 10.
Divide both the numerator and the denominator by their GCD:
[tex]\[
\frac{70 \div 10}{100 \div 10} = \frac{7}{10}
\][/tex]
So, 70% can be written as the simplified fraction:
[tex]\[
\frac{7}{10}
\][/tex]
