Transcript of Fractions And Their Use In Everyday Life

Use of Fractions In Our Daily Lives
Fractions are used daily by us in durong various tasks, such as managing time, or helping your mother cook or bake a cake.
e.g: You have to divide time on seperate tasks equally, and you have 4 tasks, and you have 4 hours to do them. To use fractions, you say that you do 1/4 of the task in 1/4 of the time, so you have 3/4 of tasks and time to complete your job.
While helping your mother bake, you will use fractions to measure out the ingredients used, i.e: 1/3 cup of milk, etc...
Uses Of Fractions in Various Professions
Fractions are also used by many people working as many different thing. Scientists and chemists use fractions to measure the right amount of a solution or chemical to use with the other ingredients to create the wanted product, i.e: 1/4 cup of water with 1/2 tablespoon of sugar, to create a sugar solution. Fractions are also used by cashiers. When the person on the cashier desk asks you for 70 1/2 AED, and you give him 71 AED, he will give you 1/2 AED back.
How To Add/Subtract Fractions
Before you can start adding a fraction, you need to make sure you have the same denominator, or the bottom number, as it is commonly known. You do this by multiplying both denominators and numerators (the numbers on the top) by a number which will give you a multiple shared by both original denominators.
You then add the numerators and keep the denominators the same
Improper Fractions
Improper fractions are fractions were the numerator is larger than the denominator. As you saw in the previous example, the answer was 5/4, which was an improper fraction. To solve this, you need to turn the fraction into a mixed number, which is a whole number with extra fractions next to it.
What Are Fractions
Fractions are quantities or numbers which are not whole numbers and are also rational numbers (numbers that can be written as a simple fraction or ratio). Fractions can be used to describe parts of something or to divide something.
Operations of Fractions And Their Use In Everyday Life
1. 1/2 + 3/4
2.You multiply the 2 by 2 to get 4 and the 1 by 2 to get 2
3. You get 2/4 + 3/4 which equals 5/4

Method of Working It Out
1. Divide the numerator by the denominator, which equals 1
2. 1 will be the whole number, and the remainder (another 1) will be the numerator of the fraction, and the denominator stays the same
Fractions are very useful in our daily lives, and learning them is a very useful and important skill in our daily lives, and helps with many daily tasks and jobs.
This is a fraction.
It is written as 1/2
or one-half
More Uses of Fractions By Scientists
Scientists also use fractions when doing their experiments. If the experiment involves time, then the person must know how to deal with fractions of a minute and fractions of a second (millisecond, picoseconds, etc.) So he can measure the results accurately and compare them easily.
Quiz Time!!
