Percentages, Fractions, and Decimal Values
Percentages are defined as a fraction or portion of a whole. Generally percentages deal with an amount out of one hundred but can be used in sales, economics, and science. If you've walked into any store you're sure to find something marked a certain percent off. Fractions are not whole numbers with a numerator over a denominator. Usually the numerator and denominator are expressed as integers. There are four types of fractions: simple fractions, complex fractions, mixed fractions, and improper fractions. Decimals are also not integers. They are expressed often like 0.34 and are often rounded off since some go for too long. Both decimals and fractions are also used to convert to percentages.

How do you change mixed repeating decimal to fraction?
First find the length of the repeating section of numbers. eg. For 0.678678678, 678 is the repeating section, and it's length is three. Divide this repeating section by the number with that many nines - for example in this case 678/999 = the fraction. Another example - 0.554755475547 = 5547/9999
What is the equivalent fraction of 7 over 70?

What fraction of all four digit natural numbers have a product of their digits that is even?
To find the fraction of four-digit natural numbers with an even product of their digits, we first note that a four-digit number ranges from 1000 to 9999, giving us a total of 9000 four-digit numbers. The product of the digits is even if at least one digit is even. The only case where the product is odd is if all four digits are odd. The odd digits are 1, 3, 5, 7, and 9, offering 5 choices for each digit. Thus, the total odd-digit combinations for four-digit numbers is (5^4 = 625). Therefore, the number of four-digit numbers with an even product is (9000 - 625 = 8375). The fraction is then ( \frac{8375}{9000} = \frac{335}{360} ), which simplifies to approximately ( \frac{67}{72} ).
How many decimal places are automatically put in percentage and dollar in excel?

Why has carbon increased by 30 percent in the last 150 years?
Carbon levels have increased by approximately 30 percent over the last 150 years primarily due to human activities, particularly the burning of fossil fuels such as coal, oil, and natural gas for energy and transportation. Deforestation and land-use changes have also contributed by reducing the number of trees that absorb carbon dioxide. Industrial processes and agricultural practices further release greenhouse gases, exacerbating the rise in atmospheric carbon levels. This increase is a key driver of climate change, leading to global warming and its associated impacts.
