When you are shopping and find a deal on 12 packs of cola advertised at 4 packs for $10. If you don't want to buy all four packs, you find the price of a single pack ($10/4packs = $2.50 per pack) or if you're throwing a party and need 16 packs you find the total cost ($10*4=$40 per 16 packs = 4 groups of 4 packs). You are using rational numbers.

Taking it a step further...

If all you have is $20, how many 12 packs can you buy? Is how we use algebra in everyday life. What number times $10 gets us $20? 2 and each of those groups are 4- 12 packs so i could get 8- 12 packs total! (our variable is not a letter...its a 12 pack of cola!)

How do you use rataional numbers in every day life?

Almost every number that almost every ordinary person uses in his personal life on almost every typical day is a rational number.


What is the role of rational and irrational number plays in modern day calculation?

Rational numbers can be expressed as fractions whereas irrational numbers can't be expressed as fractions such as the square root of 2


Where are negative numbers used in every day life?

The temperature of a fridge or a bank overdraft


How will application of real numbers and it's properties help us in real life?

Practically every application of numbers for ordinary every day real life is a real number (versus imaginary or complex numbers).Counting numbers (1,2,3,...) are natural numbers. If you use zero, then you have whole numbers. Negative numbers (used in temperature, altitude, banking, and others). Now you have the integers. Speaking of banking, with dollars and cents, you now have rational numbers (pennies are 1/100 cent). Other fractions (rational) are in use as well.Irrational numbers can be used to calculate materials needed (say you want as square with 10 square feet area, to find the perimeter: one side is square root of 10 (irrational number) then multiply by 4, to find the amount needed for all four sides. A real person would round this to whatever precision is convenient. Another commonly used irrational number is pi (rounded off to 3.1416 or so) which is used to find the area and circumference of circles.


How are integers used in your day to day life?

Integers are whole numbers, so anywhere that whole numbers are used. Calendars, groceries, hours, distances, dates, road numbers, school years, TV channels, music hit lists, box office best sellers, sports scores etc

Why rational numbers were required?

First of all counting numbers (positive integers) are rational numbers so without rational numbers there would be no counting. You could not equitably share one item between two or more people without fractions (rational numbers). Everything does not come in whole numbers - there are times when you need half-a-day, or 2.5 teaspoons, etc.

What are the uses of rational numbers in day to day life?

Any time that whole numbers are not precise enough. For example, if you want to express the length of a table in meters, the length of the table might be somewhere between 1 and 2 meters. To express the length more precisely, you need fractions (or decimals, which are a special case of fractions).
