Question

last week, you finished level 2 of a video game in 32 minutes. today, you finish level 2 in 28 minutes. what is your percent of change

Answer 1

`((32-28)/(32))*100 = 12.5%`

The general formula is;


`( (original-new)/(original) )*100`

Answer 2

The difference between these is four, and you should try and find what percentage 4 is of 32. 1/4 of 32 is 8, and as 4 is half of eight, this will be 1/8. Then convert this into a percentage, which is 12.5%
