oblicz krok po kroku: (2 3/8 + 1 5/8) : 1 1/3 = ( 2 3/8 + 1 5/8)= 1 3/7 × ( 3 3/5 - 1 4/5 × 1 1/3) = (5 1/2 + 8 3/4 + 6) : 3 = plisss na jutrooooo

(2 3/8+1 5/8):1 1/3=3 8/8 : 4/3=4 * 3/4=3 1 3/7 * (3 3/5-1 4/5 * 1 1/3)=1 3/7 * (3 3/5- 9/5 * 4/3)=10/7 * (3 3/5 - 12/5)=10/7 * (3 3/5 - 2 2/5)=10/7 * 1 1/5=10/7 * 6/5=12/7=1 5/7 (5 1/2+8 3/4+6):3=(5 2/4+8 3/4+6):3=19 5/4 :3=81/4* 1/3=27/4=6 3/4

(2 i 3/8 + 1 i 5/8) : 1 i 1/3 = 3 i 8/8 : 1 i 1/3 = 32/8 * 3/4 = 24/8 = 3 1 i 3/7 * (3 i 3/5 - 1 i 4/5 * 1 i 1/3) = 1 i 3/7 * (3 i 3/5 - 9/5 * 4/3) = 1 i 3/7 * (3 i 3/5 - 12/5) = 1 i 3/7 * (3 i 3/5 - 2 i 2/5) = 10/7 * 1 i 1/5 = 10/7 * 6/5 = 12/7 = 1 i 5/7 (5 i 1/2 + 8 i 3/4 + 6) : 3 = (5 i 2/4 + 8 i 3/4 + 6) : 3 = 19 i 5/4 : 3 = 81/4 * 1/3 = 27/4 = 6 i 3/4
