When it comes to expressing numbers in different ways, the percent is an incredibly useful form. A percent is a way to express a fraction of one hundred, and is represented by the symbol “%”. So if you are asking the question “what is 1.39 as a percent?”, you are really asking what fraction of one hundred is 1.39. To find the answer to this question, it is necessary to convert the decimal value of 1.39 into a fraction.
Converting Decimals to Fractions
To convert a decimal to a fraction, the process is fairly straightforward. First, you need to write the decimal number as a fraction. To do this, you can use the decimal point as a division sign, and place the number to the right of the decimal point in the numerator (top number) of the fraction. The denominator (bottom number) should be a number with as many zeros as there are numbers after the decimal point. In the case of 1.39, the fraction would be 139/100. Now, you can reduce the fraction to its lowest terms.
Reducing Fractions to Their Lowest Terms
The simplest way to reduce a fraction to its lowest terms is to find the greatest common factor (GCF). The GCF is the largest number that both the numerator and denominator can be divided by without a remainder. In the case of 139/100, the GCF is 1, so the fraction is already in its lowest terms. This means that 1.39 can be expressed as the fraction 139/100, or as a percent, it is equal to 139%.
Using Percentages in Everyday Life
Percentages are used in everyday life in a variety of situations. For example, when shopping, it is common to see sale items listed as a percentage off, like “30% off all shirts”. In these cases, 30% is a fraction of the original price, and is equal to 30/100. This fraction can be reduced to 3/10, or 3 out of every 10 items are discounted. Percentages are also commonly used in finance, when calculating interest rates and loan payments.
In conclusion, 1.39 is equal to the fraction 139/100, or 139%. The process of converting from a decimal to a fraction and reducing to its lowest terms is a simple one, and can be used in many different situations. Percentages are a great way to express fractions of one hundred, and are used in many different real-world scenarios.
