2、A. 1/2B. 9/10C. 4/7D. 2/9E. 5/16答案：B解题思路：0.25 + 0.65=0.9=9/103、Which of the following statements is false?A. In the fraction ½, one is the numerator.B. When 4.89 is rounded to the ones place, the answer is 5.C. Ten thousandths place is located 5 places to the right of the decimalD. 7/6 is descr

3、ibed as an improper fraction.E. 33 1/3 % is equivalent to答案：C解题思路：万分之一写为小数是0.0001，位于小数点右侧4位，所以C选项是错误的。4、Sarah needs to make a cake and some cookies. The cake requires 3/8 cup of sugar and the cookies require 3/5 cup of sugar. Sarah has 15/16 cups of sugar. Does she have enough sugar, or how much mor

4、e does she need?A. She has enough sugar.B. She needs 1/8 of a cup of sugar.C. She needs 3/80 of a cup of sugar.D. She needs 4/19 of a cup of sugar.E. She needs 1/9 of a cup of sugar.答案：C解题思路：3/8+3/5=15/40+24/40=39/40=78/80 ，15/16=75/80，75/80-78/80=3/80，所以答案为C5、There are 8 ounces in a 1/2 pound. How

5、many ounces are in 3/4 lbs?A. 12 ouncesB. 86 ouncesC. 119 ouncesD. 124 ouncesE. 138 ounces答案：A解题思路：一磅=8*2=16盎司，3/4磅=3/4*16=12盎司6、 Which of the following fractions is the equivalent of 0.5%A. 1/20B. 1/200C. 1/2000D. 1/5E. 1/500答案：A解题思路：0.5%=0.05=5/100=1/20，所以正确答案为A7、You need 4/5 cups of water for a r

7、答案为A分数的知识点分数的基本性质：一个分数的分子、分母同时乘上或除以相同的数(零除外)，分数的大小不变，这叫分数的基本性质。分数的通分、约分：通分：把异分母分数分别化成和原来分数相等的同分母分数，叫做通分。约分：把一个分数化成同它相等的，但分子和分母都比较小的分数，叫做约分。最简分数：分子和分母只有公因数1，这样的分数叫做最简分数。分数计算到最后，得数必须化成最简分数。分数的加、减法则：同分母的分数相加减，只把分子相加减，分母不变。异分母的分数相加减，先通分，然后再加减。分数大小的比较：同分母的分数相比较，分子大的大，分子小的小。异分母的分数相比较，先通分然后再比较;若分子相同，分母大的反而小。
