80 is 40% of 200 because 40%of 100 is 40. Common sense is just to double both values, also 200 x .40 (40%as a decimal) gives you the result of 80.
To help you , divide 1/4 and that will give you 0.25. 0.25 is greater than 0.15 so put the sign eating the 1/4. (Btw this is question 4)
To divide a whole number by a unit fraction, you can always multiply the whole number by the unit fraction's denominator to get the answer! Example: 5 divided by 1/7 is 5*7=35. This answer of 35 makes sense: there are seven 1/7's in a 1, so there are thirty-five 1/7's in a 5.
