розв'яжити уравнення
1/8÷х= 11/16
х×7/9= 28/45
8/13× х= 32/65

Answer 1

Ответ:

$\frac{1}{8} \div x = \frac{11}{16}$

$x = \frac{1}{8} \div \frac{11}{16}$

$x = \frac{1}{8} \times \frac{16}{11}$

$x = \frac{1}{1} \times \frac{2}{11}$

$x = \frac{2}{11}$

________________

$x \times \frac{7}{9} = \frac{28}{45}$

$x = \frac{28}{45} \div \frac{7}{9}$

$x = \frac{28}{45} \times \frac{9}{7}$

$x = \frac{4}{5}$

______________

$\frac{8}{13} \times x = \frac{32}{65}$

$x = \frac{32}{65} \div \frac{8}{13}$

$x = \frac{32}{65} \times \frac{13}{8}$

$x = \frac{4}{5}$
