Hi there, well the opposite of subtraction is addition. So we are going to add 2/5 by 1/5. 2/5+1/5=3/5, to check if we are right we do 3/5-1/5 and that would equal 1/5. Therefore, X=3/5

On a map 3 inches represent and actual distance of 42 miles if the actual distance between two cities is 322 miles how many inch

Artyom0805 [142]

Answer:

if 3 inches on a map = 42miles

then x = 322miles

cross multiply

3inches by 322 = xby42miles

966inchesmiles = 42xinchesmiles

divide both sides by 42miles

xinchees = 23

therefore 322miles distance will take 23inches on a map
