Pomocy mam to na jutro daje naj
nie piszcie samego wyniku bo musze to mieć np z zamianiami ułamków
[tex]2 \frac{5}{9} + 5.3 = [/tex]

[tex]2 \frac{2}{3} \times 1.8 = [/tex]

[tex]2 \frac{3}{20} \div 0.125 = [/tex]


Odpowiedź :

2 5/9 - 1 1/5 = 23/9 - 6/5 = 115/45 - 54/45 = 61/45 = 1 16/45
5.19 - 1 1/5 = 5.19 - 1,2 = 3.99
2 2/3 * 1.8 = 8/3 * 18/10 =144/30 = 4 24/30 = 4 12/15 = 4 4/5 = 4,8
2 3/20 / 0.125 = 43/20 / 125/1000 = 5375 / 20000 = 1075 / 4000 = 43 / 160 = 3.72
