2018年小學(xué)5年級(jí)快樂(lè)寒假作業(yè)本數(shù)學(xué)答案
(1)A、B兩個(gè)數(shù)相除,被除數(shù)、除數(shù)、商和余數(shù)的和是10。如果把被除數(shù)和除數(shù)都擴(kuò)大10倍,那么,商3余9。求A、B兩個(gè)數(shù)。
被除數(shù),除數(shù)都擴(kuò)大10倍,會(huì)使商不變,余數(shù)擴(kuò)大10倍,故ab商3余0.9.故a=3b+0.9,因?yàn)閍+b+3+0.9=10,故b=1.3, a=4.8
(2)在五個(gè)數(shù)中間加上符號(hào)或括號(hào)。
(0.1+ 0.2)0.3 +0.4-0.5=0
(0.1+ 0.2-0.3)0.4 0.5=0
[(0.1+ 0.2)0.3+ 0.4] 0.5=1
0.1 0.2-0.3+ 0.4-0.5=0.1
(3)甲、乙兩人同時(shí)從兩地出發(fā),相向而行,距離是50千米。甲每小時(shí)走3千米,乙每小時(shí)走兩千米,甲帶著一只小狗,狗每小時(shí)跑5千米。這只狗同時(shí)和甲一起出發(fā),當(dāng)它碰到乙后,便回頭跑向甲;碰到甲后又掉頭跑向乙如此下去,直到兩人向遇。小狗一共跑了多少千米?
甲乙的相遇時(shí)間是
50(3+2)=10小時(shí) 狗行的時(shí)間=甲乙的相遇時(shí)間
狗跑了
510=50千米
