Express the ratio of 12:30 as a percentage... not sure what to do to figure this out..

 

[jwpaine]

Lets say you have the ratio: 1 apple for every 2 fruit in the basket. The ratio would be 1:2 or 1/2 = 0.5 This could be expressed as 50% apples.

So, what would 12:30 be?

 

[aimeemae02]

that would be 25 but how do you know where to put the decimal point?

i divided 30 divided by 12 is that right?

or is it 12 divided by 30 which equals 40?

 

[jwpaine]

is it 12 divided by 30 which equals 40

That is correct. Because 12/30 = 0.4 which is 40%

Cheers!
