[tex]\frac{51}{12} =4\frac{1}{4}[/tex]
b)
[tex]3-1\frac{3}{5} =\frac{15}{5} -\frac{8}{5} =\frac{7}{5}=1 \frac{2}{5}[/tex]
c)
[tex]1\frac{1}{4}*5\frac{1}{3} =\frac{5}{4} *\frac{16}{3}=\frac{20}{3}=6\frac{2}{3}[/tex]
d)
[tex]1\frac{3}{5} :2\frac{2}{3}=\frac{8}{5}: \frac{8}{3}=\frac{8}{5}* \frac{3}{8} =\frac{3}{5}[/tex]
Odpowiedź:
3.
a) 1 1/12 + 5/6 + 2 1/3 = 1 1/12 + 10/12 + 2 4/12 = 3 15/12 = 4 3/12 = 4 1/4
b) 3 - 1 3/5 = 2 5/5 - 1 3/5 = 1 2/5
c) 1 1/4 * 5 1/3 = 5/4 * 16/3 = 5/1 * 4/3 = 20/3 = 6 2/3
d) 1 3/5 : 2 2/3 = 8/5 : 8/3 = 8/5 * 3/8 = 24/40 = 3/5
