Percentage

6 Sep

Hi mate,
Percentage is another easy stuff…Per cent ….mean out of one hundred …you only got to do a little things…
1/2 = 50/100 = 50 %
you see denominator of 2 and numerator of 1 ?

if you are a pizza lover… Do you like meat lover?
Start thinking you are going to invite friends to your birthday party….more people will need more pizza won’t they?

just suppose 1 is pizza and 2 is people…1 pizza for two peole
if you invite more friends to join your party mean you need more pizzas, don’t you mate?
50 people need 25 pizzas 100 people need 50 pizzas . You will not change anything if you multiply the same number for both numerator and denominator such as 1/2 = 1*25 / 2*25 = 1*40 = 2*40 …and soon. In other words people will get the same amount of pizzas as long as you follow the rule


However here, we need denominator of 2 becoming 100
1/2 is equal to 1*50 / 2* 50 = 50 (/ 100) = 50 % you know that buddy .. it is so easy, isn’t it?
therefore 1/3 = 33 1/3 % , 1/4 = 25%, 1/5 = 20 %, 1/6 = 16 2/3 %, 1/7 = 14 2/7 %, 1/8 = 12.5 % and 1/9 = 11 1/9 %…..uhhhh
not as hard as you thought ever. that’s it. I do not know why our lectures love asking the 1/8 fraction?????
so
3/8 = 3 * (1/8) = 3*12.5 % = 37.5 %
5/8 = 5 * (1/8) = 5*12.5 % = 62.5 %
7/8 = 7 * (1/8) = 7*12.5 % = 87.5 %
