1/3 into percent and into decimals

also tell me the steps

To get a percentage out of 1/3, you want to divide 100 by 3, giving you 33.3% (the 3 recurring) and for a decimal you divide 1 by 3, giving you 0.3 (recurring)

If i think this is what your asking, he should look at the grams or pounds/ounces and compare the to their cost then max can identify which one is proportional and which is not ( i think xd)
