Question

Aprēķini proporcijas nezināmo locekļi!

Answer 1

а) 
$2:x=24:7$
$24*x=2*7$
$24x=14$
$x=\frac{14}{24}=\frac{7}{12}$

б)
$12:35=x:7$
$35*x=12*7$
$35x=84$
$x=2,4$

в)
$\frac{7}{4}=\frac{x}{5}$
$4*x=7*5$
$4x=35$
$x=8,75$

г)
$\frac{5}{y}=\frac{35}{11}$
$35*y=5*11$
$35y=55$
$y=\frac{55}{35}=\frac{11}{7}$
