5). 6/7
6). 2/3, 2/6, 2/5, 2/10, 2/15
7). 3/4*X=114
X= 114*4/3
X= 152cm
8). 5/8*16kodi=... buah
5/8*(16*20)
=5/8*320
=200
9). 3/8*(14*12)
= 3/8*168
=63
10). 4/9*X=32000
X= 32000*9/4
X= 72000

3/8*72000
= 27000

11). 5¼+3
= 21/4 + 12/4
= 33/4
= 8¼

12). 5 3/5 - 2 1/4
= 28/5 - 9/4
= 112/20 - 45/20
= 67/20
= 3 7/20

13). 2 2/6* 2 4/10
= 14/6*24/10
= 7/3*12/5
= 84/15
= 5 9/15
= 5 3/5

14). 1 6/9: 3 2/6
= 15/9 : 20/6
= 15/9 * 6/20
= 1/2
