Zadanie 6.
b.
[tex]4 \frac{1}{3} \div \frac{3}{5} = \frac{13}{3} \div \frac{3}{5} = \frac{13}{3} \times \frac{5}{3} = \frac{65}{9} = 7 \frac{2}{9} [/tex]
c.
[tex]3 \frac{3}{4} \div \frac{2}{3} = \frac{15}{4} \div \frac{2}{3} = \frac{15}{4} \times \frac{3}{2} = \frac{45}{8} = 5 \frac{5}{8} [/tex]
d.
[tex]1 \frac{1}{2} \div 1 \frac{2}{3} = \frac{3}{2} \div \frac{5}{3} = \frac{3}{2} \times \frac{3}{5} = \frac{9}{10} [/tex]
e.
[tex] \frac{4}{5} \div 1 \frac{1}{6} = \frac{4}{5} \div \frac{7}{6} = \frac{4}{5} \times \frac{6}{7} = \frac{24}{35} [/tex]
f.
[tex] \frac{9}{20} \div 2 \frac{5}{7} = \frac{9}{20} \div \frac{19}{7} = \frac{9}{20} \times \frac{7}{19} = \frac{63}{380} [/tex]
zrobiłam tylko te, które miałaś zaznaczone, jakby co, zrobię resztę (jeżeli będziesz potrzebowała)
