Mengulas ulang dasar-dasar membagi pecahan, dan cobalah beberapa soal latihan.

Pembagian pecahan

Membagi pecahan adalah sama dengan mengalikan dengan kebalikan dari pecahan tersebut.
Sebagai contoh:
start fraction, 3, divided by, 4, end fraction, start color #e07d10, divided by, end color #e07d10, start fraction, start color #11accd, 2, end color #11accd, divided by, start color #1fab54, 3, end color #1fab54, end fractionequals, start fraction, 3, divided by, 4, end fraction, start color #e07d10, times, end color #e07d10, start fraction, start color #1fab54, 3, end color #1fab54, divided by, start color #11accd, 2, end color #11accd, end fraction
Setelah kita mendapatkan soal perkalian, kita kalikan pembilang kemudian kalikan penyebutnya.
Contoh 1: Pecahan
start fraction, 3, divided by, 2, end fraction, divided by, start fraction, 8, divided by, 3, end fraction, equals, question mark
Kebalikan start fraction, 8, divided by, 3, end fraction dari start fraction, 3, divided by, 8, end fraction.
Sehingga:
start fraction, 3, divided by, 2, end fraction, divided by, start fraction, 8, divided by, 3, end fraction, equals, start fraction, 3, divided by, 2, end fraction, times, start fraction, 3, divided by, 8, end fraction
empty space, equals, start fraction, 3, times, 3, divided by, 2, times, 8, end fraction
empty space, equals, start fraction, 9, divided by, 16, end fraction
Contoh 2: Pecahan campuran
3, start fraction, 1, divided by, 2, end fraction, divided by, 1, start fraction, 1, divided by, 4, end fraction, equals
Mari mulai dengan mengubah pecahan campuran menjadi pecahan biasa.
empty space, 3, start fraction, 1, divided by, 2, end fraction, divided by, 1, start fraction, 1, divided by, 4, end fraction
equals, start fraction, 7, divided by, 2, end fraction, divided by, start fraction, 5, divided by, 4, end fraction
equals, start fraction, 7, divided by, 2, end fraction, dot, start fraction, 4, divided by, 5, end fraction, space, space, space, space, space, space, space, start text, K, a, l, i, k, a, n, space, d, e, n, g, a, n, space, k, e, b, a, l, i, k, a, n, n, y, a, point, end text
equals, start fraction, 7, divided by, start color #11accd, 1, end color #11accd, start cancel, 2, end cancel, end fraction, dot, start fraction, start color #11accd, 2, end color #11accd, start cancel, 4, end cancel, divided by, 5, end fraction, space, space, space, space, space, space, space, start text, S, e, d, e, r, h, a, n, a, k, a, n, point, end text
equals, start fraction, 7, divided by, start color #11accd, 1, end color #11accd, end fraction, dot, start fraction, start color #11accd, 2, end color #11accd, divided by, 5, end fraction
equals, start fraction, 14, divided by, 5, end fraction, start text, space, a, t, a, u, space, end text, 2, start fraction, 4, divided by, 5, end fraction
