Odpowiedź:
[tex]22-(3\frac{1}{2} *2+4\frac{3}{4}) =22-(7+4\frac{3}{4} )=22-11\frac{3}{4} =10\frac{1}{4}[/tex]
[tex]4\frac{2}{3} :2+4\frac{2}{5} *5=\frac{14}{3} *\frac{1}{2} +\frac{22}{5} *\frac{5}{1} =\frac{7}{3} +22=24\frac{1}{3}[/tex]
22 - (3 1/2 * 2 + 4 3/4) = 22 - (7/2 * 2 + 4 3/4) = 22 - (7 + 4 3/4) = 22 - 11 3/4 =
= 10 1/4
4 2/3 : 2 + 4 2/5 * 5 = 14/3 * 1/2 + 22/5 * 5 = 14/6 + 22 = 2 2/6 + 22 =
= 2 1/3 + 22 = 24 1/3
