问题 What is the decimal equivalent of (1/4)2 ?
选项 A、0.0016
B、0.0625
C、0.16
D、0.25
E、0.5
答案B
解析 To square a fraction, we have to square both the numerator and the denominator, which gives us 1/16. If you want to avoid the long division, you can just divide 1 by 2, which gives you 1/2 or 0.5. Divide again and you get 1/4 or 0.25. Keep going until you get to 1/16 or 0.0625.
