Question

X: 5 целых 23= 1 целая 79: 1 целая 727

Answer 1

$x:5frac{2}{3}=1frac{7}{9}:1frac{7}{27}\\x:frac{17}{3}=frac{16}{9}: frac{34}{27}\\xcdot frac{3}{17}=frac{16}{9}cdot frac{27}{34}\\xcdot frac{3}{17}=frac{8cdot 3}{17}\\x=frac{8cdot 3}{17}: frac{3}{17}\\x=frac{8cdot 3}{17}cdot frac{17}{3}\\x=8$
