Question

Допоможіть будь ласка зробити 1,3,5​

Answer 1

Ответ:

$\frac{19}{50} - x = \frac{3}{20}$

$- x = \frac{3}{20} - \frac{19}{50}$

$- x = \frac{15 - 38} {100}$

$x = \frac{23}{100}$

$x = - 0.05 = \frac{7}{30}$

$x = \frac{7}{30} + \frac{5}{100}$

$x = \frac{70 + 15}{300}$

$x = \frac{85}{300}$

$x = \frac{17}{60}$

$1.5x = \frac{15}{16}$

$x = \frac{15}{16} \div \frac{3}{2}$

$x = \frac{15}{16} \times \frac{2}{3}$

$x = \frac{5}{8}$
