1. Mary is twelve years old. Her father is four times(四倍) as old as her. Her grandfather is twice (两倍) as old as her father. How old is her grandfather? He is
96 years old
.
答案:【解析】:本题主要考查乘法的实际应用以及年龄的计算。
首先,根据题目描述,Mary是12岁。
接着,题目说她的父亲是她的四倍年龄,所以父亲的年龄就是$12 × 4 = 48(岁)$。
然后,题目又说她的祖父是她的父亲年龄的两倍,所以祖父的年龄就是$48 × 2 = 96(岁)$。
因此,我们可以通过乘法运算得出祖父的年龄。
【答案】:96 years old.
2. Ann and Bill have five sweets. Bill and Clare have four sweets. Clare and Ann have three sweets. Ann has
2
sweet(s). Bill has
3
sweet(s). Clare has
1
sweet(s). Ann, Bill and Clare have
6
sweet(s).
答案:【解析】:
这是一个关于线性方程组的问题,但由于是五年级的题目,我们不会使用复杂的方程组来解答。我们可以通过设立等式,利用加减法来求解。
设Ann有a个糖果,Bill有b个糖果,Clare有c个糖果。
根据题意我们可以得出以下等式:
Ann和Bill共有5个糖果,即 a + b = 5。
Bill和Clare共有4个糖果,即 b + c = 4。
Clare和Ann共有3个糖果,即 c + a = 3。
将这三个等式相加,得到 2(a + b + c) = 12,即 a + b + c = 6。
现在我们可以通过这个等式和之前的等式来求解a,b,c的值。
首先,从 a + b = 5 和 a + b + c = 6 中,我们可以得出 c = 1。
然后,从 b + c = 4 中,我们可以得出 b = 3(因为c已经求出为1)。
最后,从 c + a = 3 中,我们可以得出 a = 2(因为c已经求出为1)。
【答案】:
Ann has $2$ sweet(s).
Bill has $3$ sweet(s).
Clare has $1$ sweet(s).
Ann, Bill and Clare have $6$ sweet(s).
3. Mike is standing in Group One. There are fifteen students in front of him and thirteen students behind him. How many students are there in Group One? There are
29
students.
答案:15 + 13 + 1 = 29
There are 29 students.
4. If an astronaut has a weight of 72 kg on the Earth, he will have a weight of 12 kg on the Moon. If another astronaut has a weight of 10.5 kg on the Moon, the astronaut's weight will be
63 kg
on the Earth.
答案:63 kg。
5. Lucy goes out for a walk from her home. She walks 4 km east, 3 km south and 4 km west. How far is she from her home now? ______
3 km

A.11 km.
B.8 km.
C.4 km.
D.3 km.
答案:【解析】:
这个问题是一个典型的位移和距离问题,需要用到空间想象和基本的数学运算。Lucy从家里出发,先向东走了4km,然后向南走了3km,最后向西走了4km。我们可以通过画图来帮助理解这个问题。
1. Lucy起始于家(我们可以设这个点为原点(0,0))。
2. 她先向东走了4km,到达点(4,0)。
3. 然后向南走了3km,到达点(4,-3)。
4. 最后向西走了4km,到达点(0,-3)。
通过画图,我们可以清晰地看到Lucy现在的位置是在她家的正南3km处。因此,我们可以通过计算得出她现在离家的直线距离。
由于Lucy最终的位置是在家的正南方,所以我们可以直接通过计算南北方向的位移来得出她离家的距离,即3km。
【答案】:D
6. “团购”也疯狂,做智慧购物达人。
“Group Buying” allows people to buy things at a lower price. One day, you and your friends go into a restaurant which provides the service of “Group Buying”. And you only have to spend 85 yuan to get a ticket with the value(价值) of 100. If all the food you order costs 160 yuan, using
1
ticket(s) will be the cheapest way.
A.0
B.1
C.2
D.3
答案:【解析】:
这个问题是一个实际应用问题,涉及到数学中的基本运算和逻辑推理。题目描述了“团购”的情境,其中提到使用团购票可以以低于面值的价格购买到价值更高的商品或服务。具体来说,在这个问题中,人们可以花费85元购买价值100元的票。接下来,我们需要计算在不同数量的票的使用情况下,实际支付的总金额是多少,并找出最便宜的方式。
首先,我们计算不使用团购票的情况下的总支出,即160元。
然后,我们考虑使用团购票的情况:
1. 如果使用1张团购票,那么需要支付85元购买票,并且票可以覆盖100元的消费,所以还需要额外支付160 - 100 = 60元。因此,总支出是85 + 60 = 145元。
2. 如果使用2张团购票,那么需要支付2 * 85 = 170元购买票,但票的总价值是200元,已经超过了实际消费的160元,所以不需要额外支付。但考虑到我们只需要160元的服务,购买2张票会造成浪费,实际有效支付是170元(因为多余的部分没有被使用)。
3. 如果使用3张团购票,支付金额会更高,造成更大的浪费。
最后,我们比较这些支出,找出最低支出对应的团购票数量。
【答案】:
B
