So, we've got two important and useful information: guy's house is 9/10 miles away from the library guy's house is 4/10 miles away from the cafe now, the question will tell us which mathematical operation to use, it says: how much farther than. that means comparing which means difference which means subtraction. (how much farther than=comparing=differnce=subtraction) so now we know that we will subtract. but, subtact which number from which number? we need to subtract 4/10 from 9/10 which means it will be equal to 5/10 which can be simplified into 1/2 the answer is basically 5/10 and if you want to look smart for your teacher, you must write simplified=1/2..
hopw this helps... now.. for return i need the brainliest answer.. :) :D
