Question

Реши уравнение: 2 1/15 - 3/4 y = 59/60

Answer 1

Пошаговое объяснение:

$2\frac{1}{15} - \frac{3}{4}y = \frac{59}{60}$

$\frac{3}{4}y = 2\frac{1}{15} - \frac{59}{60}$

$\frac{3}{4}y = \frac{31}{15} - \frac{59}{60}$

$\frac{3}{4}y = \frac{124}{60} - \frac{59}{60}\\$

$\frac{3}{4}y = \frac{65}{60} \\$

$\frac{3}{4}y = \frac{13}{12}$

$y = \frac{13}{12} : \frac{3}{4}$

$y = \frac{13}{12} * \frac{4}{3}$

$y = \frac{13}{9}$

$y = 1\frac{4}{9}$
