问题 0.25 ×=_____
选项
答案 1/20
解析 First convert 1/5 to its decimal equivalent, which is .2. Then multiply .25 by .2 to get .05. Another way to solve is to first convert .25 to its equivalent fraction, which is 1/4. When multiplying the two fractions, you first multiply the numerators, and then the denominators, giving you 1/20. Because this is equivalent to .05, either answer will be correct.
