Question

решите уравнение 34/60+8/60+y=41/60+16/60​

Answer 1

Ответ:

$\displaystyle y=\frac{15}{60}$

Пошаговое объяснение:

$\displaystyle \frac{34}{60}+\frac{8}{60} +y=\frac{41}{60}+\frac{16}{60}\\\\\frac{34+8}{60}+y=\frac{41+16}{60}\\\\\frac{42}{60}+y=\frac{57}{60}\\\\y=\frac{57}{60}-\frac{42}{60}\\\\y=\frac{57-42}{60}\\\\y=\frac{15}{60}$

                                           

$\displaystyle \frac{34}{60}+\frac{8}{60} +\frac{15}{60} =\frac{41}{60}+\frac{16}{60}\\\\\ \qquad$

             $\displaystyle\frac{57}{60}=\frac{57}{60}$
