Question

2 1/2=1 2/3:у , 4•m=3 3/7 , 24 12/19=6•n

Answer 1

$2 \frac{1}{2} = 1 \frac{2}{3} \div y$

$2 \frac{1}{2} = 1 \frac{2}{3} + y,y = 0$

$\frac{5}{2} = \frac{5}{3} \times \frac{1}{y}$

$\frac{5}{2} = \frac{5}{3y}$

$15y = 10$

$y = \frac{2}{3} ,y = 0$

$y = \frac{2}{3}$

________________________________

$4 \times m = 3 \frac{3}{7}$

$4m = \frac{24}{7}$

$m = \frac{6}{7}$

________________________________

$24 \frac{12}{19} = 6 \times n$

$\frac{465}{19} = 6n$

$6n = \frac{468}{19}$

$n = \frac{78}{19}$
