. . . 1 . . .
Step 1: 60/x=100/85
Step 2: (60/x)*x=(100/85)*x
Step 3: 60=1.17647058824*x
Step 4: (1.17647058824) to get x
Step 5: 60/1.17647058824=x
Step 6: 51=x
The correct answer for the first one is x = 51.
. . . 2 . . .
Step 1: 45/x=100/35
Step 2: (45/x)*x=(100/35)*x
Step 3: 45=2.85714285714*x
Step 4: (2.85714285714) to get x
Step 5: 45/2.85714285714=x
Step 6: 15.75=x
Therefore, the second answer will be x = 15.75.
I hope I helped you! :)
