Bardzo bardzo proszę matma klasa 6 !!
daje naj
pozdrawiam ​

Answer 1

Witaj!

2 1/3 + 5/6 * 3/5 = 7/3 + 5/6 * 3/5 = 7/3 + 3/6 = 14/6 + 3/6 = 2 5/6

7 - 4/5 : 2 1/2 = 7 - 4/5 * 2/3 = 7 - 8/15 = 6 7/15

1 1/4 * 1 3/5 - (0.6 - 0.55) = 5/4 * 8/5 - 0.15 = 2 - 0.15 = 1.85

4 1/2 * 2/3 - 1/4 = 9/2 * 2/3 - 1/4 = 3 - 1/4 = 2 3/4

Odpowiedź:

a)[tex]2\frac{1}{3} +\frac{5}{6} *\frac{3}{5} =2\frac{1}{3} +\frac{1}{2} =2\frac{2}{6}+ \frac{3}{6} =2\frac{5}{6}[/tex]

b)[tex]7-\frac{4}{5} :2\frac{1}{2} =7-\frac{4}{5} :\frac{5}{2} =7-\frac{4}{5} *\frac{2}{5} =7-\frac{8}{25} =6\frac{17}{25}[/tex]

c)[tex]1\frac{1}{4} *1\frac{3}{5} -(0,6-0,55)=\frac{5}{4} *\frac{8}{5}-0,05=2-0,05=1,95[/tex]

d)[tex]4\frac{1}{2} *\frac{2}{3} -\frac{1}{4} =\frac{9}{2} *\frac{2}{3} -\frac{1}{4} =3-\frac{1}{4} =2\frac{3}{4}[/tex]
