Решите уравнения А)p+4/19=1 Б)1-p=15/23 В)p+16/25=1 Г)1-p=7/18

Решите задачу:

$1) p = 1- \frac{4}{19} = \frac{19}{19} - \frac{4}{19} = \frac{19-4}{19} = \frac{15}{19}$
$2) p = 1- \frac{15}{23} = \frac{23}{23} - \frac{15}{23} = \frac{23-15}{23} = \frac{8}{23}$
$3) p = 1- \frac{16}{25} = \frac{25}{25} - \frac{16}{25} = \frac{25-16}{25} = \frac{9}{25}$
$4) p = 1- \frac{7}{18} = \frac{18}{18} - \frac{7}{18} = \frac{18-7}{18} = \frac{11}{18}$
