Question

РЕШИТЕ УРАВНЕНИЕ 2/7X= 2 2/7 ,3/5y=2 9/10-1/5

Answer 1

  2/7X= 2 2/7
  x = 16/7 * 7/2
  x = 8

  3/5y=2 9/10-1/5
  3/5y = 29/10 - 1/5
  3/5y = (29 - 2)/10
  3/5y = 27/10
  y = 27/10 * 5/3
  y = 9/2 = 4 1/2

Answer 2

$frac{2}{7} x=2 frac{2}{7}$
$frac{2}{7} x= frac{16}{7}$
$x= frac{16}{7} * frac{7}{2}$
$x=8$
--------------------
$frac{3}{5} y=2 frac{9}{10} - frac{1}{5}$
$frac{3}{5} y=2 frac{7}{10}$
$y= frac{27}{10} * frac{5}{3}$
$y= frac{9}{2}$
$y=4 frac{1}{2}$
