a)
[tex]12 \frac{1}{4} - 8 \frac{1}{4} = 4[/tex]
b)
[tex]2 \frac{2 }{5} + 3 \frac{1}{2} = 2 \frac{4}{10} + 3 \frac{5}{10} = 5 \frac{9}{10} [/tex]
c)
[tex]3 \frac{1}{3} - 2 \frac{1}{8} = 3 \frac{8}{24} - 2 \frac{3}{24} = 1 \frac{5}{24} [/tex]
d)
[tex]4 \frac{1}{2} + 1 \frac{1}{6} = 4 \frac{6}{12} + 1 \frac{2}{12} = 5 \frac{8}{12} = 5 \frac{2}{3} [/tex]
e)
[tex]7 - \frac{1}{2} - \frac{1}{4} = 6 \frac{1}{2} - \frac{1}{4} = 6\frac{2}{4} - \frac{1}{4} = 6 \frac{1}{4} [/tex]
f)
[tex]5 \frac{5}{13} - 3 \frac{1}{2} = 5 \frac{10}{26} - 3 \frac{13}{26} = 4 \frac{36}{26} - 3 \frac{13}{26} = 1 \frac{23}{26} [/tex]
g)
[tex]3 \frac{1}{4} + 2 \frac{2}{5} + 3 \frac{4}{2} = 3 \frac{5}{20} + 2 \frac{8}{20} + 3 \frac{40}{20} = 8 \frac{53}{20} = 10 \frac{13}{20} [/tex]
Myślę że pomogłem ;)
