1、精選優(yōu)質(zhì)文檔-傾情為你奉上SSAT數(shù)學(xué)經(jīng)典試題（分?jǐn)?shù)部分）SSAT數(shù)學(xué)部分是中國(guó)考生最為關(guān)注及重視的，為了加深SSAT數(shù)學(xué)分?jǐn)?shù)部分的了解，我們搜集到了以下8道SSAT數(shù)學(xué)經(jīng)典試題，并提供了權(quán)威的答案及解析，快來(lái)查看我們整理的SSAT數(shù)學(xué)試題吧！SSAT數(shù)學(xué)經(jīng)典試題（分?jǐn)?shù)部分）1、Which of the following is not a fraction equivalent to 3/4?A. 6/8B. 9/12C. 12/18D. 21/28E. 27/36答案：C解題思路：分子分母同乘以一個(gè)數(shù)，分?jǐn)?shù)的值不變，所以不等于3/4的數(shù)是12/18。2、Solve: 0.25 + 0.65

2、A. 1/2B. 9/10C. 4/7D. 2/9E. 5/16答案：B解題思路：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解題思路：萬(wàn)分之一寫為小數(shù)是0.0001，位于小數(shù)點(diǎn)右側(cè)4位，所以C選項(xiàng)是錯(cuò)誤的。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解題思路：3/8+3/5=15/40+24/40=39/40=78/80 ，15/16=75/80，75/80-78/80=3/80，所以答案為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解題思路：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解題思路：0.5%=0.05=5/100=1/20，所以正確答案為A7、You need 4/5 cups of water for a r

6、ecipe. You accidentally put 1/3 cups into the mixing bowl with the dry ingredients. How much more water in cups do you need to add?A. 1/3 cupsB. 2/3 cupsC. 1/15 cupsD. 7/15 cupsE. 7/16 cups答案：D解題思路：4/5-1/3-=12/15-5/15=7/15，所以答案為D8、3/4-1/2=A. 1/4B. 1/3C. 1/2D. 2/3E. 2/5答案：A解題思路：3/4-1/2=3/4-2/4=1/4，所以

7、答案為A分?jǐn)?shù)的知識(shí)點(diǎn)分?jǐn)?shù)的基本性質(zhì)：一個(gè)分?jǐn)?shù)的分子、分母同時(shí)乘上或除以相同的數(shù)(零除外)，分?jǐn)?shù)的大小不變，這叫分?jǐn)?shù)的基本性質(zhì)。分?jǐn)?shù)的通分、約分：通分：把異分母分?jǐn)?shù)分別化成和原來(lái)分?jǐn)?shù)相等的同分母分?jǐn)?shù)，叫做通分。約分：把一個(gè)分?jǐn)?shù)化成同它相等的，但分子和分母都比較小的分?jǐn)?shù)，叫做約分。最簡(jiǎn)分?jǐn)?shù)：分子和分母只有公因數(shù)1，這樣的分?jǐn)?shù)叫做最簡(jiǎn)分?jǐn)?shù)。分?jǐn)?shù)計(jì)算到最后，得數(shù)必須化成最簡(jiǎn)分?jǐn)?shù)。分?jǐn)?shù)的加、減法則：同分母的分?jǐn)?shù)相加減，只把分子相加減，分母不變。異分母的分?jǐn)?shù)相加減，先通分，然后再加減。分?jǐn)?shù)大小的比較：同分母的分?jǐn)?shù)相比較，分子大的大，分子小的小。異分母的分?jǐn)?shù)相比較，先通分然后再比較;若分子相同，分母大的反而小。
