Question

Решите пропорцию:
5 3/5 : 3 1/2 = 5 1/4 : x

Answer 1

$frac{5frac{3}{5}}{3frac{1}{2}}=frac{5frac{1}{4}}{x}\x=frac{3frac{1}{2}*5frac{1}{4}}{5frac{3}{5}}=frac{7}{2}*frac{21}{4}*frac{5}{28}=frac{105}{32}=3frac{9}{32}$

Answer 2

5 3/5 : 3 1/2 = 5 1/4 : x
28/5*х=7/2*21/4
х=7/2*21/4*5/28
х=105/32
х=3 9/32
