✔ 最佳答案
1 .32 = 2 x 2 x 2 x 2 x 2
48 = 2 x 2 x 2 x 2 x 3
56 = 2 x 2 x 2 x 7
HCF = 2 x 2 x 2 = 8
LCM = 2 x 2 x 2 x 2 x 2 x 3 x 7 = 672
2.
0.1 = 1/10
0.375 = 375/1000 = 3/8
1.6 = 1 + 6/10 = 1又3/5
2.13 = 2 + 13/100 = 2又13/100
3.
30/66 = 10/33
32/256 = 1/8
4.
3/25 = 12/100 = 0.12
3又9/40 = 129/40 = 3.225
5.
0.75 = 75/100 = 3/4
7.35 = 7 + 35/100 = 7又7/20
6.
1公升 = 1000毫升
1000 - (1000 x 1/4) - 368
= 1000 - 250 - 368
= 382
7.
x + (x+2) = 86
2x + 2 =86
2x=84
x = 42
