Cześć!
Zamiast kropeczek, będzie kwadracik
Podpunkt a)
[tex]\frac{5}{6}+\square=1\\\\\square=1-\frac{5}{6}\\\\\square=\frac{6}{6}-\frac{5}{6}\\\\\boxed{\square=\frac{1}{6}}\\\\---------\\\\\frac{5}{6}+\square=5\\\\\square=5-\frac{5}{6}\\\\\square=4\frac{6}{6}-\frac{5}{6}\\\\\boxed{\square=4\frac{1}{6}}[/tex]
Podpunkt b)
[tex]\frac{8}{9}+\square=1\\\\\square=1-\frac{8}{9}\\\\\square=\frac{9}{9}-\frac{8}{9}\\\\\boxed{\square=\frac{1}{9}}\\\\--------\\\\\frac{8}{9}+\square=4\\\\\square=4-\frac{8}{9}\\\\\square=3\frac{9}{9}-\frac{8}{9}\\\\\boxed{\square=3\frac{1}{9}}[/tex]
Podpunkt c)
[tex]\frac{5}{12}+\square=1\\\\\square=1-\frac{5}{12}\\\\\square=\frac{12}{12}-\frac{5}{12}\\\\\boxed{\square=\frac{7}{12}}\\\\--------\\\\\frac{5}{12}+\square=7\\\\\square=7-\frac{5}{12}\\\\\square=6\frac{12}{12}-\frac{5}{12}\\\\\boxed{\square=6\frac{7}{12}}[/tex]
Mam nadzieję, że rozjaśniłam Ci jak wykonywać tego typu zadania, jeśli masz problem z policzeniem tego w pamięci.
