szybciutkooooo plis A. oblicz iloczyn wynik doprowadź do najprostszej postaci a) 3/4 * 8/15 b) 3 1/3 * 2/5 c) 5/6 * 1 2/7 d) 1 1/2 * 2 1/6 e) 4 2/7 * 0,4 B.oblicz iloraz wynik doprowadź do najprostsze postaci a) 8/9 : 2/3 b) 1 1/4 : 5/7 c) 8/15 :

a) 3/4 × 8/15 = 24/60 = 4/10 = 2/5 b) 3 1/3 × 2/5 = 10/3 × 2/5 = 20/15 = 1 5/15 = 1 1/3 c) 5/6 × 1 2/7 = 5/6 × 9/7 = 45/42 = 1 3/42 1 1/14 d) 11/2 × 2 1/6 = 11/2 × 13/6 = 146/12 = 12 2/12 = 12 1/6 e) 2/7 × 0,4 = 2/7 × 4/10 = 8/70 = 4/35 a) 8/9 : 2/3 = 9/8 × 3/2 = 27/16 = 1 11/16 b) 11/4 : 5/7 = 4/11 × 7/5 = 28/55 c) 8/15 : 3 1/5 = 8/15 : 16/5 = 15/8 × 5/16 = 75/128 d) 2 1/2 : 1 2/3 = 5/2 : 5/3 = 2/5 × 3/5 = 6/25 e) 1,8 : 3/4 = 18/10 : 3/4 = 10/18 × 4/3 = 40/54 mam nadzieję, ze pomiglam, liczę na naj!:)
