:(  calculate each mountain path grade to the nearest percent. path a: for every 3535 meters of horizontal distance, the vertical change is 1414 meters path b: for every 4.26 meters of horizontal distance, the vertical change is 22 meters the grade of path a= % the grade of path b= %

The grade of the path in the mountain is calculated by determining first the ratio between the rise over the run and multiplying the ratio by 100%. 

For Path A: 

                 grade = (rise / run) x 100%
                 grade = (1414/ 3535) x 100% = 40%

40%

For Path B:
              grade = (rise / run) x 100%
              grade = (4.26 m/ 22 m) x 100% = 19.36%

19.36%
