數(shù)學(xué)考試是不是難點(diǎn)?下面是小編為大家搜索整理的有關(guān)備考新gre數(shù)學(xué)易錯(cuò)題型解析，大家在備考新gre數(shù)學(xué)考試時(shí)可以根據(jù)以下所提到的易錯(cuò)題型為自己查漏補(bǔ)缺，新gre數(shù)學(xué)解題技巧是考生朋友們需要了解的。

　　1 the sum of two numbers, x and y, equals twice their products. if x=3, what is the value of y?

　　這道題沒(méi)大看懂?請(qǐng)問(wèn)大家是這樣么?x+y=2

　　x+y=2xy,求y.

　　2 if x is an integer and x237,what is the greatest possible value of x minus the least possible value of x?

　　我覺(jué)得這道題x的最大值為6,最小值為0,所以選6.

　　a.5 b.6 c.10 d.12 e.36

　　選D，最大為6，最小為-6.

　　3 三角形ABC，角B=X度，X90 度，比較三角形的周長(zhǎng)與3倍AC的長(zhǎng)度的大小，答案是B

　　AC是最大邊,所以AB+BC+AC

　　2.0

　　比較the greatest value of p與1/2的大小，答案是C

　　答案錯(cuò)了,選B p+=2p^1/2 ==1/4 1/2

　　4 for the line with equation y=ax+b,the x-intercept os twice the y-intercept

　　比較the slope of the line 與1/2的大小，答案是D，但算出來(lái)是-1/2呀

　　還有截距為零的情況,所以D.

　　5 a certain moneymarket account that had a balance of $48000 during all of last monthearned $360 in interest for the month. at what simple annual interestrate did the account earn interest last month?

　　答案是9%,題目沒(méi)看懂獲得更多gre考試咨詢(xún)點(diǎn)擊進(jìn)入

　　36012/48000=9%

　　6 Of the positive integers that are multiples of 30 and are less than or equal to 360,what fraction are multiples of 12?

　　a.1/6 b.1/5 c.1/3 d.2/5 e.1/2

　　首先這道題我是對(duì)multilples of ....不大明白,這是什么意思啊?其次這道題怎么解呢?

　　在小于360的30的公倍數(shù)中,也是12的公倍數(shù)的占多少?30N360, 得N12,所以共有12個(gè)數(shù)滿足題干.

　　又12與30的最小公倍數(shù)為60,其實(shí)此題是求是60的倍數(shù)又小于等于360所占比例,同理求出為6

　　所以,6/12=答案E

　　7 A certain teacher has a total ofat least 110 students enrolled in her classes.if the teachers has anaverage of exactly 27 students enrolled per class.what is the least possible number of classes that the teacher couldhave?

　　a.3 b.4 c.5 d.6 e.7

　　我覺(jué)得這道題就是用110除以27就好了,可是答案是選c的

　　是呀，110/27=4.04,如果是4個(gè)班，那么總?cè)藬?shù)為108，還剩2個(gè)。當(dāng)然是5個(gè)班了。

　　8 a delivery service charges $0.02 per ounce for the first 16 ounces ofa shipment and $0.15 for each additional ounce of theshipment,

　　the delivery charges for x shipments weighing a combimed total of the pounds vs 567.00

　　這道題答案選的是D,不明白怎么會(huì)無(wú)法確定呢?我是這樣算的:160.2+0.15...這樣對(duì)么? 分頁(yè)標(biāo)題#e#

　　因?yàn)閤是個(gè)未知數(shù)，所以你無(wú)法確定它的值。

　　9 the cost per gram of carrots if 3 cans of carrots cost $0.90 the costper gram of onions if 5 cans of onions cost $1.50

　　無(wú)法確定，沒(méi)有告訴1can有多少克?

　　10 X is an integer, and the remainder when 2X is divided by 4 is 0.

　　The remainder when X is divided by 4 0

　　選D，當(dāng)x=2，-2時(shí)，余數(shù)為2，-2，其它情況為0

　　以上即是備考新gre數(shù)學(xué)解題易出錯(cuò)10個(gè)題型介紹，希望對(duì)大家的新gre數(shù)學(xué)考試有所幫助。
