Question

решите уравнения 15/64x=25;5 1/3x=8 8/9;3 2/5y=6 4/5;9 1/2y=14 1/4

Answer 1

15/64х = 25
х = 25 : 15/64
х = 320/3
х = 106  2/3
-------------------------
5  1/3 х = 8 8/9
х = 8 8/9 : 5  1/3
х = 80/9 : 16/3
х = 5/3 = 1  2/3
-------------------------
3  2/5у = 6  4/5
17/5у = 34/5
у = 34/5 : 17/5
у = 2
------------------------
9  1/2у = 14  1/4
19/2у = 57/4
у = 57/4 : 19/2
у = 3/2 = 1  1/2
