Question

Решите уравнение (1,7÷(х-10,25))×21 1/4=2 5/6

Answer 1

( 1,7 : ( Х - 10,25 )) • 21 1/4 = 2 5/6
1,7 : ( Х - 10,25 ) = 2 5/6 : 21 1/4
2 5/6 : 21 1/4 = 17/6 : 85/4 = 34/255
1,7 : ( Х - 10,25 ) = 24/255
Х - 10,25 = 1,7 : ( 24/255 )
1,7 : ( 24/255 ) = 17/10 : ( 24/255 ) = 289/16 = 18,0625
Х - 10,25 = 18,0625
Х = 18,0625 + 10,25
Х = 28,3125
