Ответ:

0,25

$\frac{33}{70}$

$\frac{10}{46}$

Пошаговое объяснение:

34/60+8/60+у=41/60+16/60

$\frac{34}{60} + \frac{8}{60} + y = \frac{41}{60} + \frac{16}{60} \\\\\frac{42}{60} + y = \frac{57}{60} \\\\y = \frac{57}{60} - \frac{42}{60} \\\\y = \frac{15}{60} \\\\y = 0, 25$

64/70-(х+26/70)=5/70
$\frac{64}{70} - (x + \frac{26}{70} ) = \frac{5}{70} \\\\\frac{64}{70} - x - \frac{26}{70} = \frac{5}{70} \\\\\frac{38}{70} - x = \frac{5}{70} \\\\-x = \frac{5}{70} - \frac{38}{70} \\\\-x = \frac{-33}{70} \\\\x = \frac{33}{70}$

х+27/46=35/46+2/46

$x + \frac{27}{46} = \frac{35}{46} + \frac{2}{46} \\\\x + \frac{27}{46} = \frac{37}{46} \\\\x = \frac{37}{46} - \frac{27}{46} \\\\x = \frac{10}{46}$
