Textbook Question

Write each percent as a fraction. Give answers in lowest terms.
$140 percent sign$

Verified step by step guidance

Understand that a percent means 'per hundred,' so 140% can be written as the fraction $ \frac{140}{100} $.

Write the fraction $ \frac{140}{100} $ to represent 140%.

Simplify the fraction by finding the greatest common divisor (GCD) of 140 and 100.

Divide both the numerator and the denominator by their GCD to reduce the fraction to its lowest terms.

Express the simplified fraction as the final answer representing 140% in fraction form.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Understanding Percentages

A percentage represents a part out of 100. Writing 140% means 140 per 100, or 140 divided by 100. Recognizing this helps convert percentages into fractions by expressing the percent value over 100.

Converting Percent to Fraction

To convert a percent to a fraction, write the percent number as the numerator and 100 as the denominator. For example, 140% becomes 140/100. This fraction can then be simplified to its lowest terms.

Simplifying Fractions

Simplifying fractions involves dividing the numerator and denominator by their greatest common divisor (GCD). This reduces the fraction to its simplest form, making it easier to understand and use in further calculations.
