How do i convert a fraction ( 7/8 ) to miles, based on a map scale ?
Based on the map, 1 inch = 75 miles.
By measuring a city to mt everest, i got 7/8 on a ruler.
How do i convert this to miles ? and then to kilometers ? Thanks
Thanks everyone !!
75 miles divided by 7/8 = 65.625
65.625 X 1.609 = 105.613km
