两倍的估计 = anggaran 2 kali 看图：橙线和绿线比，大约长多少倍？看出倍数，再用参照距离乘这个倍数。估计的答案要带“大约”。 例子：参照 55 km，大约两倍长就是大约 110 km。 注意：不要只看线的终点名字，要比较线的长度。

estimating twice = anggaran 2 kali Look at the diagram: about how many times as long as the green line is the orange line? Multiply the reference distance by that. An estimate always says about. Example: with a 55 km reference, about twice as long is about 110 km. Watch out: compare the lengths of the lines, not just the place names.

一半的估计 = anggaran separuh 橙线比绿线短，大约只有它的一半。一半就是把参照距离平均分成两份，取其中一份。答案要比参照小。 例子：参照 70 km，大约一半就是大约 35 km。 注意：线变短就要用除法，不是乘法。

estimating half = anggaran separuh The orange line is shorter than the green one, about half as long. Half means sharing the reference distance into two equal parts and taking one. The estimate must be smaller than the reference. Example: with a 70 km reference, about half is about 35 km. Watch out: a shorter line needs dividing, not multiplying.

一半用除法 = separuh, bahagi 2 题目已经告诉你，要找的距离大约是已知距离的一半。把已知距离除以 2，就是估计的距离。算好以后检查：答案应该比已知距离小。 例子：已知 12 km，一半大约 6 km。 注意：一半不是减 2，也不是乘 2。

half means divide = separuh, bahagi 2 The question says the distance is about half of the known distance. Divide the known distance by 2 to get the estimate. Then check that the estimate is smaller than the known distance. Example: half of a known 12 km is about 6 km. Watch out: half is not taking away 2, and not multiplying by 2.

找出对应的地点 = cari tempat yang sepadan 先想一想：题目问的距离是参照距离的几倍？算出倍数后，再在图上找长度差不多是绿线那么多倍的线。那条线的终点就是答案。 例子：参照 30 km，要找大约 15 km 的地方，就找大约一半长的线。 注意：每条线都要和绿线比，不要只看哪条最长。

finding the matching place = cari tempat yang sepadan First work out how many times the reference distance the question's distance is. Then look for the line that is about that many times as long as the green line. The place at the end of that line is the one. Example: with a 30 km reference, a place about 15 km away has a line about half as long. Watch out: compare every line with the green one; do not just choose the longest.

估计弯路 = anggar laluan berliku 弯曲的路线不能只看头尾。沿着橙色的路走，每到一个小圆点就是一段，每一段大约和绿色参照线一样长。数出一共有几段，再用参照距离乘段数，答案前面加“大约”。 例子：参照 20 km，弯路分成 5 段，距离大约 100 km。 注意：起点和终点之间的直线比弯路短，不能拿来估计。

estimating a winding road = anggar laluan berliku A winding road cannot be judged by its two ends alone. Follow the orange road; each small dot marks the end of a part, and each part is about as long as the green reference line. Count the parts, multiply the reference distance by that number, and say about. Example: with a 20 km reference and a road of 5 parts, the distance is about 100 km. Watch out: the straight gap between the ends is shorter than the road, so do not use it.
