Question

300 is what percent of 150?.

Answer 1

300 : x = 150 : 100
x = 300 * 100 : 150
x = 200
------------
200%

Answer 2

We can use algebra to solve this.
Let the percentage be P%.
From the given information,
150 x P% = 300
Flip x150 to the other side and turn it into ÷150
P% = 300 / 150
P% = 2
We can turn a whole number into decimal form by moving the decimal place of it 2 places to the right.
In 2, the decimal is behind 2, which makes it 2.0
So when we move the decimal place to 2 places to the right,
The answer would be 200%
