Contoh perkalian pecahan bagian 1
1. 2/3 x 2/5 = …
2. 3/4 x 5/6 = …
3. 3/5 x 1/2 = …
4. 5/8 x 2/7 = …
5. 5/7 x 7/8 = …
6. 4/9 x 2/3 = …
7. 3/2 x 2/3 = …
8. 4/6 x 5/8 = …
9. 6/7 x 3/6 = …
10. 8/9 x 3/4 = …
Jawaban
1. 2/3 x 1/4 = (2 x 1) / (3 x 4) = 2/12 = 1/6
2. 3/4 x 5/6 = (3 x 5) / (4 x 6) = 15/24 = 5/8
3. 3/5 x 1/2 = (3 x 1) / (5 x 2) = 3/10
4. 5/8 x 2/7 = (5 x 2) / (8 x 7) = 10/56 = 5/28
5. 5/7 x 7/8 = (5 x 7) / (7 x 8) = 35/56 = 5/8
6. 4/9 x 2/3 = (4 x 2) / (9 x 3) = 8/27
7. 3/2 x 2/3 = (3 x 2) / (2 x 3) = 5/6
8. 4/6 x 5/8 = (4 x 5) / (6 x 8) = 20/48 = 5/12
9. 6/7 x 3/6 = (6 x 3) / (7 x 6) = 18/42 = 3/7
10. 8/9 x 3/4 = (8 x 3) / (9 x 4) = 24/36 = 2/3
Contoh perkalian dua pecahan campuran bagian 2
1. 2 2/3 x 5 =
= 8/3 x 5
= (8 x 5)/3
= 40/3
= 13 1/3
2. 1 4/5 x 2 =
= 9/5 x 2
= (9 x 2)/5
= 18/5
= 3 3/5
3. 5 x 1 3/7 =
= 5 x 10/7
= 50/7
= 7 1/7
4. 100 x 1 2/3 =
= 100 x 5/3
= 500/3
= 166 2/3
5. 5/8 x 1 3/4 =
= 5/8 x 7/4
= (5 x 7)/(8 x 4)
= 35/32
= 1 3/32
Itulah cara menghitung perkalian pecahan, teruslah berlatih agar bisa cepat memahaminya.
