# How many time is 40 more than 30?

would be really grateful if someone can explain which of the 2 methods is the right way to answer this question and also why:

Method 1:

40-30=10

10/30=0.33x

40 is more than 30 by 0.33 times

Method 2:

40/30=1.33

40 is more than 30 by 1.33 times

Both seem correct to me but I can't identify what's the difference.

Your first method is correct. I could suggest modifying that second formula. Try using this instead:

40/30 - 1

It is as much a grammar issue as it is mathematics. Forty is (about) 0.33 times more than 30. It is 1.33 times as much as 30.

I can never look at problems like this without recalling that guy who used to sell peanuts outside the ballpark for what he claimed was 700% less than the stadium price, which would make sense only if he paid people to take his peanuts.

How many times is 40 more than 30?

2 methods to answer this question:

Method 1:

40 - 30 = 10

10 / 30 = 0.33x

40 is more than 30 by 0.33 times

(40 - 30)/30 = 0.33

Method 2:

40 / 30 = 1.33

40 is more than 30 by 1.33 times

40 is 1.33 times 30
