问题 1/3+3/7=______
选项
答案  You must first find the Lowest Common Denominator (LCD) for the two fractions involved. The denominators are 3 and 7. The smallest number into which both of these numbers can divide evenly is 21. Convert each denominator to 21 by multiplying 1/3 by 7/7 and 3/7 by 3/3 . This gives you 7/21+9/21 which equals 16/21.
