√2 percent of 2√2 = Choose one.
A) 5.0
B) 0.05
C) 1.0
D) 2.0
E) 4.0
The other solutions are great, but here's one more approach.   First, we scan the answer choices to see that they are quite spread apart. This means we can also use someAPPROXIMATION   All test-takers must memorize the following approximations:   √2 ≈ 1.4   So, √2 percent of 2√2 ≈ 1.4 percent of (2)(1.4)   ≈ (1.4/100)(2.8)   ≈ 3.92/100   ≈ 0.03   Check the answer choices to see that B is the only answer that's close.   Answer: 0.05
