a)
[tex] 3 \frac{3}{8 } + 1 \frac{1} {8} = 4 \frac{4}{8} = 4 \frac{1}{2} [/tex]
b)
[tex] \frac{3}{10} \div \frac{5}{6} = \frac{3}{10} \times \frac{6}{5} = \frac{3}{5} \times \frac{3}{5} = \frac{9}{25} [/tex]
c)
[tex] \frac{14}{15} \div \frac{7}{10} = \frac{14}{15} \times \frac{10}{7} = \frac{2}{3} \times \frac{2}{1} = \frac{4}{3} = 1 \frac{1}{3} [/tex]
d)
[tex]1.2 + \frac{3}{4} = 1.2 + 0.75 = 1.95[/tex]
e)
[tex]7 \frac{3}{5} - 0.8 = 7 \frac{6}{10} - 0.8 = 6 \frac{16}{10} - 0.8 = 6 \frac{8}{10} = 6 \frac{4}{5} [/tex]
Myślę że pomogłem ;)
