5.7 is what % greater than 5.2?

at first I thought
5.2x = 5.7 solve for x
x=1.096...

**X is not in a % form right?
I'm missing a step..i can see "9.6" in my way..but what is left out?

then someone said (5.7-5.2)/5.2*100 = 9.6%

???

second calculation is right. Apply the % change formula.

New minus Old divided by Old

Your question is formulated incorrectly imo.

5.7 is 109.6% of 5.2

or 5.2 is 91.2% of 5.7

I believe you're looking for the difference between one of these and 100%, so 9.6% or 8.8%. I would go with 9.6 from what you've written.

thanks guys

You got the same thing bud. The multiplier 1.096 > 1 which means that it's a larger number than what you started with (5.2) and the remainder is the percentage that it's larger than. so, it's 0.096 bigger. But, you still have to convert it into a percentage: 0.096*100 = 9.6 percent.
