pakai cara soal matematika no 4 sampai 9

4). 20 4/5 - 6/7 - 11 31/35 - 0,5=
104/5 - 6/7 - 416/35 - 5/10 =
7280/350 - 300/350 - 4160/350 - 175/350 =
2645/350 : 5/5 = 529/70 = 7 39/70

5). 3 2/4 x 5 1/7 x 0,35 =
14/4 x 36/7 x 35/100 =
126/500 : 2/2 = 63/250

6). 12,5 : 0,5 =
125/10 : 5/10=
125/10 x 10/5 = 25/1 = 25

7). 4,16 : 0,4 : 1,3 =
416/100 : 4/10 : 13/10 =
416/100 x 10/4 x 10/13 = 8/1 = 8

8). 5/8 : 5 15/6 : 0,25 : 65% =
5/8 : 45/6 : 25/100 : 65/100 =
5/8 x 6/45 x 100/25 x 100/65 =
600/1170 : 30/30.= 20/39

9). 5 1/5 - 2 ¼ x 0,5 + 45% =
26/5 - 9/4 x 5/10 + 45/100 =
26/5 - 45/40 + 45/100 =
2080/400 - 450/400 + 180/400 =
1810/400 : 10/10 = 181/40 = 4 21/40
