tolong bantu. sifat sifat bilangan pecahan itu apa saja yaaa ???

sifat bilangan pecahan apa dulu?

* sifat bilangan pecahan perkalian
1. sifat tertutup ~ contohnya : (2/5) x (8/11) = 16/55
2. sifat komutatif ~ contohnya : p x q = q x p
3. sifat asosiatif atau pengelompokkan ~ contohnya : 2/5 × (–2/7 × 3/5) = [2/5 ×(–2/7)] × 3/5 = –12/175

* sifat bilangan pecahan perkalian dan penjumlahan
1. sifat distributif ~ contohnya : 6/3 x [5/3 + (–4/3)] = 6/3 × 1/3 = 6/9 
    (6/3 × 5/3) + [6/3 × (–4/3)] = 30/9 – 24/9 = 6/9
    Jadi, 6/3 × [5/3 + (–4/3)] = (6/3 × 5/3) + [6/3 × (–4/3)] = 2/9

* sifat bilangan pecahan perkalian dan pengurangan
1. sifat distributif ~ contohnya : 4/5 × [6/5 – (–5/5)] = 4/5 × 11/5 = 44/25
    (4/5 × 6/5) – [4/5 × (–5/5)] = 24/25 – (–20/25) = 44/25
    Jadi, 4/5 × [6/5 – (–5/5)] = (4/5 × 6/5) – [4/5 × (–5/5)] = 44/25

kalau ada yg salah mohon maaf yah...
sekian dan terima kasih :)
