We all probably know that when we hear percentage we think of 100.

So here are 5 amazing tricks that can help to find percentage of some numbers without the use of a calculator.

So let's begin

We'll start with some tips

1. Tip -1-

15% of 300 =45

Step 1- Calculate 10%

300/10 = 30

Step 2- Calculate 5% of the answer from Step 1.

5% of 30= 15

Step 3- Add step 1 and 2

30+15= 45

2. 5% of numbers

-1-

5% of 60= 3

Step 1- Divide the number by 10

60/10 = 6

Step 2- Divide the number from Step 1 by 2

6/2 = 3

3. 20% of numbers 

-1-

20% of 255= 51

Step 1- 20% = (100/5)%

Step 2- 255/5 = 51

Step 3- 5=10/2

Step 4- Divide the number by 10

255/10 = 25.5

Step 5- Multiply the number from Step 4 by 2

25.5 × 2=51

-2-

20% of 255 = 51

Step 1- Divide the number by 10

255/10 = 25.5

Step 2- Multiply the number from Step 1

25.5×2 = 51

4. 25% of numbers 

-1-

25% of 64= 16

Step 1- 25% = (100/4)%

Step 2- Divide the number by 4

64/4 = 16

Fig 5.

5. 50% of numbers 

-1-

50% of 64 = 32

Step 1- 50%= 100/2

Step 2- Divide the number by 2

64/2 = 32

But seriously why do we always keep our focus on 5 sub topics per lesson🤔

Maybe it's because we have five fingers on each hand and five toes on each foot and we also have the five senses😅😅

But seriously why🤔
