What % of 3 1/3 is 6 1/4? I'm stuck ...

You can manipulate the number to make them easier to handle

3 and 1/3 times 12=36+4=40

6 and 1/4 times 12=72+3=75

so is 40=100% then wha is 75

40 and 75

divide by 2

20 and 37.5

multiply by 5

100 and 187.5

100=100% and 187.5=187.5%

187.5-100=87.5%

87.5% increase
