start by \(3300\div 11=300\) so each inch is 300 miles

then divide \(6300\div 300\) to compute miles to inches

each inch represents a certain number of miles since \(3300\) miles is represented by 11 inches, you know each inch represents \(3300\div 11=300\) miles, i.e. one inch represents 300 miles is that okay so far?

now you have \(6300\) miles, and you want to know how many inches that would be on the map

since each inch is 300 miles, you want to know \(300x=6300\) or more easily stated as you want to know what is \(3600\div 300\)

i think that's ok ..

ok but just to make sure it is clear 1 inch is 300 miles 2 inches is 600 miles 3 inches is 900 miles etc in other words, \(x\) inches is \(300x\) miles you have \(6300\) miles to convert to inches, so you want to know what you would multiply 300 by to get \(6300\) which is just another way of saying, what is \(6300\div 300\)
