Proszę w miarę szybko ​


Odpowiedź :

[tex] \frac{3}{4} \div \frac{1}{7} = \frac{3}{4} \times \frac{7}{1} = \frac{21}{4} = 5\frac{1}{4} [/tex]

[tex] \frac{7}{9} \div \frac{7}{9} = \frac{7}{9} \times \frac{9}{7} = 1[/tex]

[tex] \frac{4}{15} \div \frac{8}{9} = \frac{4}{15} \times \frac{9}{8} = \frac{1}{5} \times \frac{3}{2} = \frac{3}{10} [/tex]

[tex]5 \frac{5}{6} \div 2 \frac{1}{3} = \frac{35}{6} \div \frac{7}{3} = \frac{35}{6} \times \frac{3}{7} = \frac{5}{2} \times \frac{1}{1} = \frac{5}{2} = 2 \frac{1}{2} [/tex]

[tex]2 \frac{2}{3} \div 3 \frac{1}{5} = \frac{8}{3} \div \frac{16}{5} = \frac{8}{3} \times \frac{5}{16} = \frac{1}{3} \times \frac{5}{2} = \frac{5}{6} [/tex]

[tex]4 \frac{3}{8} \div \frac{ 5 }{8} = \frac{35}{8} \times \frac{8}{5} = \frac{7}{1} \times \frac{1}{1} = 7[/tex]

Myślę że pomogłem ;)

Szczegółowe wyjaśnienie:

3/4:1/7=3/4*7=21/4=5 1/4

7/9:7/9=7/9*9/7=1

4/15:8/9=4/15*9/8=3/10

5 5/6:2 1/3=35/6: 7/3=35/6*3/7=5/2=2 1/2

2 2/3:3 1/5=8/3:16/5=8/3*5/16=5/6

4 3/8:5/8=35/8:5/8=35/8*8/5=7
