The 60% length of a road is 75 km. How do you find the total
2016年12月26日 · The total length of the road is 125 km We can rewrite this problem as: 60% of what is 75 km? "Percent" or "%" means "out of 100" or "per 100", Therefore 60% can be written as 60/100. When dealing with percents the word "of" means "times" or "to multiply". Finally, lets call the number we are looking for "l". Putting this altogether we can write this equation and solve for l while keeping the ...
