Hej
Szczegółowe wyjaśnienie:
[tex] \frac{21}{8} + 6 - ( \frac{10}{3} - \frac{7}{4} ) + (7 - \frac{43}{12} ) = \frac{21}{8} + 6 - \frac{19}{12} + \frac{41}{12} = \frac{251}{24} = 10 \frac{11}{24} [/tex]
2 5/8+6-(3 1/3-1 3/4)+(7-3 7/12)=2 5/8+6-(3 4/12-1 9/12)+(6 12/12-3 7/12)=
=2 5/8+6-(2 16/12-1 9/12)+3 5/12=2 5/8+6-1 7/12+3 5/12=
=8 5/8-1 7/12+3 5/12=8 15/24-1 14/24+3 10/24=7 1/24+3 10/24=10 11/24
