Question

Решите уравнения x+8 цел 1/11=16,1 . y - 9.7 =8 цел 2/3, 100,3+x= 102 цел 1/6

Answer 1

$x+8\tt\displaystyle\frac{1}{11}=16,1\\\\$

$x+8\tt\displaystyle\frac{1}{11}=16\frac{1}{10}\\\\$

$x=16\tt\displaystyle\frac{1}{10}-8\frac{1}{11}\\\\$

$x=16\tt\displaystyle\frac{11}{110}-8\frac{10}{110}\\\\$

$x=8\tt\displaystyle\frac{1}{110}\\\\$

===================

$y-9,7=8\tt\displaystyle\frac{2}{3}\\\\$

$y=8\tt\displaystyle\frac{2}{3}+9,7\\\\$

$y=8\tt\displaystyle\frac{2}{3}+9\frac{7}{10}\\\\$

$y=8\tt\displaystyle\frac{20}{30}+9\frac{21}{30}\\\\$

$y=17\tt\displaystyle\frac{41}{30}\\\\$

$y=18\tt\displaystyle\frac{11}{30}\\\\$

===================

$100,3+x=102\tt\displaystyle\frac{1}{6}\\\\$

$100\tt\displaystyle\frac{3}{10}+x=102\frac{1}{6}\\\\$

$x=102\tt\displaystyle\frac{1}{6}-100\frac{3}{10}\\\\$

$x=102\tt\displaystyle\frac{5}{30}-100\frac{9}{30}\\\\$

$x=101\tt\displaystyle\frac{35}{30}-100\frac{9}{30}\\\\$

$x=1\tt\displaystyle\frac{26}{30}\\\\$

$x=1\tt\displaystyle\frac{13}{15}$
