Yah half is equals to increased by 50%

Answer 1

Given :  Few statement regarding a variable & operation on it

To find : Statement is true or false

Solution:

A increased by 100%= 2a   - TRUE

=> a  + (100/100)a  = a  + a = 2A

A decreased by hundred percent is equals to 2 a  - False

a  - (100/100)a = a - a =  0

200% of a is equals to increased by 20%  - FALSE

200 % of a = (200/100)a = 2a

a + (20/100)a  =  1.2a

2a ≠ 1.2a

0% of a equals to zero  - TRUE

(0/100)a = 0

Half  a  is equals to increased by 50%  - FALSE

Half a = a/2 = 0.5a

a + (50/100)a  = 1.5a

0.5a ≠ 1.5a

One & Half  a  is equals to increased by 50%  - TRUE

one & Half a = 3a/2 = 1.5a

a + (50/100)a  = 1.5a

1.5a = 1.5a
