(2*1/3+2i1/2*2)*3/4=

kto pierwszy ten najlepszy

Answer 1

2-1i1/2*2/5=2-3/5=1⅖

(2i1/2+4i1/6):1i1/3-1/8=6⅔:1⅓-⅛=5-⅛=4⅞

3+1i1/5*3/4=3+0,9=3,9

(2i2/6-1i1/3)*2i1/4-1/6=1*2¼-⅙=2¼-⅙=2i1/12

(2*1/3+2i1/2*2)*3/4=(⅔+5)*¾=5⅔*¾=4¼

 

Answer 2

2 - 3/2 * 2/5 = 2 - 3/5 = 1 i 2/5

(5/2 + 25/6):4/3 - 1/8 = (15/6 + 25/6):4/3 - 1/8 = 40/6 * 3/4 -1/8 = 10/2 - 1/8 = 40/8 - 1/8 = 39/8 = 4 i 7/8

3 + 6/5* 3/4 = 3 + 9/10 = 3 i 9/10

(14/6 - 4/3)* 9/4 - 1/6 = (14/6 - 8/6) * 9/4 - 1/6 = 1 * 9/4 - 1/6 = 9/4 - 1/6 = 27/12 - 2/12 = 25/12

(2*1/3 + 2*5/2)*3/4 = (2/3 + 5)*3/4 = 5 i 2/3 * 3/4 = 17/3 * 3/4 = 17/4
