Jawaban dan pembahasan untuk 1-8
1. 2/5 x 3/7 = 2*3/5*7 = 6/35
2. 1 ⅔ x 1 ½
1 ⅔ = 5/3
1 ½ = 3/2
5/3 x 3/2 = 5*3/3*2 = 15/6
3. 0,15 x 2,8
0,15 = 15/100 = 3/20
2,8 = 28/10 = 14/5
3/20 x 14/5 = 42/100 = 0,42
4. 2 ⅗ x 4,3
2⅗ = 13/5
4,3 = 43/10
13/5 x 43/10 = 559/50
5. 1/8 : 2/5
= 1/8 x 5/2 = 5/16
6. 4⅙ : 2/3
4 ⅙ = 25/6
25/6 : 2/3 =
25/6 x 3/2 = 75/12
7. 5,8 : 2,5
5,8 = 58/10
2,5 = 25/10
58/10 : 25/10 =
58/10 x 10/25 = 580/250 = 58/25
8. 6,125 : 1¾
6,125 = 6125/1000
1¾ = 7/4
6125/1000 : 7/4 =
6125/1000 x 4/7 =24.500/7000 = 245/70
