Again, finding 7% is tricky, but finding 200% is simple, so switch the problem around: 7% of 200 = 200% of 7. Above, you learned that to find 200% of any number, you just multiply that number by 2: 7% of 200 = 200% of 7 = 2 7 = 14. Solve more-difficult percent problems. You can solve a lot of percent problems using the tricks shown above.
