Percentages in Our Life
Percentages in real world
Keywords: math, divide, percentage, interest, persent change Around the year 1260, the philosopher Roger Bacon wrote: “Mathematics is the door and the key to the sciences... for the things of this world cannot be made known without a knowledge of mathematics”. Centuries later this is as true as ever.
Mathematics is unique. It is both a beautiful and fascinating world of abstract structures and ideas and a down-to-earth, practical subject at the heart of modern science and technology. Much of its attraction comes from studying the relationship between theory and practice – an elegant theorem on complex functions, for example, also governs the lift on an aircraft wing, and apparently highly abstract algebraic results have important consequences in data security.
There is one of the way to express how large/small one quantity is, relative to another quantity in math we use percentage. A percentage is a part of something expressed as a value out of a hundred. Percentages are an important part of our everyday lives. Some examples include: sales and discounts interest rates percentage chance of rainfall exam results statistics and survey results sports statistics.
Percentage is a very handy way of writing fractions.
Percentages can be compared more easily than fractions(fraction (from Latin: fractus, "broken") represents a part of a whole or, more generally, any number of equal parts, for example, one-half, eight-fifths, three-quarters).
A percent can always be written as a decimal, and a decimal can be written as a percent, by moving the decimal point two places to the right.
The history of percentages goes back to the ancient Egyptians who wrote numbers (based on tens) alongside pictures called hieroglyphs. The idea of expressing parts of the whole are constantly in the same proportions, due to practical considerations, was born in ancient times from the Babylonians, who used the sexagesimal fractions.
