人教版六年级下册数学书练习三的答案全部
方法1解决方案:让阅读材料,合共X页
5/7x = 35
X = 49
2 35÷5/7 = 49(页)
2方法1:解决方案:设立一个成年人每天大约X克钙.
3/8x = 3/10
所述2:3 / 10 = 4/5
方法÷3/8 = 4/5(G)
3解决方案1解决方案:让我们的飞船速度为x千米/秒.
40/57x = 8
40/57x÷40/57 = 8÷40/57
X = 57/5
解决方案2 8÷4?0/57 = 57/5 (公里/秒)
4.解决方案:让水桶粗细x公斤
x-1/10x = 9
(1-1/10)= 9
X = 9÷9/10
X = 10
方法
2 9÷(1-1/10)= 10(公斤)5 15/16÷3 = 15/16×1/5 = 3/16 12/25÷8 = 12 / 25×1/8 = 3/50
8÷4/5 = 8×4/5 = 10 21/40÷7/8 = 21/40×8/10 = 3/5
16÷2/17 = 16×17/2 = 136 7/24÷6/49 = 7/24×17/2 =一百四十四分之三百四十三
18 / 35÷0.6×2/3 4/9×15/16÷5/6
= 35/18×10/6×2/3 = 5/12×6/5
= 6/7 ×2/3 = 1/2
= 12/21 = 4/7
(2-0.6)÷7/15 35/64÷(1/8 +3 / 4)
= 1.4×15/7 = 35/64÷8分之7
= 3 = 35/64×8/7 =
八分之五
6(1500 +1000) ×3/5 = 1500(元)
7.48 +48÷4/5 = 108(万台)
8.5200÷52/55 = 5500(公里
9(1)24÷1/2 = 48(件)
一等奖:48×1/6 = 8(件)
二等奖:48 1/3 = 16(件)
(2)48÷120 = 2/5
10.3/5x = 1/6×16/51 = 25/72 8/9x /> 3/5x÷3/5 = 25/72÷五分之三8/9x÷8/9 =一百五十三分之八÷九分之八
=二百一十六分之一百二十五= 1/17
的
所述÷6/35 = 26/45÷13/25
所述÷6/35×6/35 = 10/9×6/35
X = 4/21
> 11 2/10÷4 = 1/10(1-2/5)÷1/10 = 6(汽车)
12(1),28÷1/5 = 140() x-1/46 = 9000
(1-1/46)= 9000
45/46x = 9000
45/46x÷45/46 = 9000÷45/46号
X = 9200
