VEDIC MATHS

                           By OMKAR TENDOLKAR

Hello friends,

                      This is  post number 90 from the series of "Vedic maths" blogs. Here in this blog we will learn about "Percentage"

Percentage:
In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. 

If we have to calculate percent of a number, divide the number by whole and multiply by 100. Hence, the percentage means, a part per hundred. 

The word per cent means per 100. It represented by the symbol “%”.

Converting Percentages into Fractions:

1. Convert 80% into a fraction.

We first convert 80% into a fraction like this, 80% = 80/100 = 4/5.
We have also reduced the fraction to 80 / 100 its simplest form, which is 4/5.
Answer :
80% = 4/5.

2. Convert 40% into a fraction.

We first convert 40% into a fraction like this, 40% = 40/100 = 2/5.
We have also reduced the fraction to 80 / 100 its simplest form, which is 2/5.
Answer :
40% = 2/5.

3. Convert 65% into a fraction.

We first convert 65% into a fraction like this, 65% = 65/100 = 13/20.
We have also reduced the fraction to 65 / 100 its simplest form, which is 13/20.
Answer :
65% = 13/20.

Converting Fractions into Percentages:

1.  Say we have to convert 3 / 4 into a percentage.

So this is what we do:
3/4 * 100 = 3 * 25 = 75%
Answer :
3 /4 = 75%.

2. Say we have to convert 2 / 5 into a percentage.

So this is what we do:
2/5 * 100 = 2 * 20 = 40%
Answer :
2 / 5 = 40%.

3. Say we have to convert 17 / 20 into a percentage.

So this is what we do:
17/20 * 100 = 17 * 5 = 85%
Answer :
17 /20 = 85%.

Converting Percentages into Decimals:

1. Say we have to convert 45.6% into a decimal.

So what we do is shift the decimal point two places to the left. So our answer is:
45.6/100 = 0.456
Answer :
45.6% = 0.456.

2. Say we have to convert 8.09% into a decimal.

So what we do is shift the decimal point two places to the left. So our answer is:
8.09/100 = 0.0809
Answer :
8.09% = 0.0809.

3. Say we have to convert 0.674% into a decimal.

So what we do is shift the decimal point two places to the left. So our answer is:
0.674/100 = 0.00674
Answer :
0.674% = 0.00674.


Solve the following example.
1. Convert 75% into a fraction.
Ans : 75% = 75 / 100 = 3 / 4.

2. convert into 7/10 a percentage.
Ans : 7/10 * 100 = 7 * 10 = 70%

3. convert 45% into a decimal.
Ans :  45 / 100 = 9 / 20 = 4.5 / 10 = 0.45.

The simplicity of this method can be vouched from examples given above.

You may try following examples.
1. Convert 21% into a fraction.
2. Convert 33% into a fraction.
3. convert into 3/10 a percentage.
4. convert into 8/10 a percentage.
5. convert 47% into a decimal.
6. convert 50% into a decimal.

In next blog we will discuss about "Algebraic Calculations-I".     

Are you excited for this?...
Then, please wait for it.
I will post my new blog in next week.

We will meet very soon through our next  blog. Till that stay connected, stay healthy and stay safe.

Thanks

for giving your valuable time.

Good day😊

  VEDIC MATHS                             By OMKAR TENDOLKAR Hello friends,                        I am Omkar Tendolkar from Kudal. I am studying in S.Y.B.Sc at SRM College, Kudal. I always enjoy sharing my knowledge. This is one of my attempts.            Some people find mathematics challenging to understand, while others struggle with calculations. Certainly, the comprehension of the subject depend on IQ (intelligent quotient), but equally crucial is one's perspective towards it. Because mastering calculation doesn't solely rely on a sharpe IQ; it also demands some basic tricks that can greatly assist in handling complex calculations.                  Starting today, I want to launch a "VEDIC MATHS" blog. Here, you will find a series of blog's explaining simple tricks that will...

VEDIC MATHS                             By OMKAR TENDOLKAR Hello friends,                          This is our first blog in the series of 'Vedic Maths' blogs. Here, we will learn about the basic principles required in Vedic Maths. This blog will cover all the fundamental concepts necessary for understanding our next few blogs.   Base: It is the first number in the series. For a two-digit number: 10. Starting with 10, 100, 1000, 10000, etc. Complement: . Adding two numbers results in the next nearest base. 48 + 52 = 100. Then, We can say that 48 is the complement of 52 or 52 is the complement of 48. How to find: Subtract each digit from 9 and the last digit from 10. If... The last digit is 0, then take the second-to-last digit as the last one. For example: 60 is the complement of 40. All these examples, ranging from 2 digits to 6 digits, w...

  VEDIC MATHS                             By OMKAR TENDOLKA R Hello friends,                       This is our 15th blog from the series of "Vedic maths" blogs. Here in this blog we will learn about   "Criss-Cross System of Multiplication " . Criss-Cross System of Multiplication :                In Vedic Mathematics , we have similar system as like traditional way of multiplication it helps us to get the answer much faster. This system is also universal system and can be used for any combination of numbers of any length.                      This system of Multiplication is given by the " Urdhva-Tiryak Sutra. " It means ' vertically and cross-wise '. The application of this system are manifold, but in this blog we shall confine our study only to it's utility in...
