First, convert 2843in to feet. This is done by taking 2843/12=236.917 ft. Then, to go from feet to miles, the conversion is 5280ft/mile, so take 236.917/5280 to obtain .044871 miles. MILES would be the numerator
There are 90 cm in 900 mm. When converting from cm to mm, move the decimal 1 place to the left.

Inches
You would place "centimeters" in numerator and "centimeters per inch" in the denominator. (centimeters)/(centimeters/inch) = [(centimeters) x (inch)] / [centimeters] which yields "inch(es)"
