Answer 2

3. 3 1/2 x 4/8=7/2 x 4/8 = 28/16 = 7/4
5. 3 1/2 x 0,09= 7/2 x 9/100 = 63/200
Ubahlah bentuk %
6.4,15=4,15 x 100% = 450%
7.8,9= 8,9 x 100% = 890%
8.4 5/8= 37/8 x 100% = 37 x 12,5% = 462,5%
9.3/12= 3/12 x 100% = 1/4 x 100% = 25%
10.3 3/50= 153/50 x 100% = 306%
Ubahlah kepecahan biasa!
11.2,15= 2 15/100 = 2 3/20 atau 63/20
12.15%= 15/100 = 3/20
13.87,5%= 87,5/100 = 875/1000 = 35/40 = 7/8
14.4 75/500= 2075/500 = 83/20
15.0,008= 8/1000 = 1/125
Ubahlah bentuk desimal
16.3 4/8=3 1/2 = 3,5
17.7,5%= 7,5/100 = 0,075
18.8 7/14 = 8 1/2 = 8,5
19.125% = 125/100 = 1,25
20.16/400 =0,04
