Question

помогите пжлста 2⅓k=4½*1целая 1 девятая

Answer 1

$2 frac{1}{3} k= 4frac{1}{2} * 1frac{1}{9} \ frac{7}{3} k= frac{9*10}{2*9} \ frac{7}{3} k=5 \ k= frac{5*3}{7} \ k=2 frac{1}{7}$

Answer 2

2 13k = 4 12 x 1 19   4 12 = 92   1 19 = 109   2 13 = 73
 k = 4 12 x 1 19 ; 2 13=92 x 109 x37= 157 = 2 17
k = 2 17
