5 3/5:3 1/2 = 5 1/4: 2х

Answer 1

5 3/5:3 1/2 = 5 1/4: 2х

28/5 : 7/2 = 21/4 : 2х
2х*28/5  = 21/4* 7/2
х=21*7*5/(4*2*2*28)=735/448

Answer 2

5 3/5:3 1/2 = 5 1/4: 2х

28/5 : 7/2 = 21/4 : 2х
2х = (21/4* 7/2 )/ (28/5)
х=21*7*5/(4*2*2*28)=735/448=(7*105)/(7*64) = 105/64

Answer 3

5ц 3/5:3ц 1/2 = 5ц 1/4: 2х
28/5 :7/2=21/4:2х
28/5*2/7=21/4*1/2х
8/5=21/8х
х=21/8:8/5=21/8*5/8=105/64=1 ц  41/64
