Question

Помогите решить пример:
4 1/4y-(1 7/12y+3/8y), если y=48;y=1 3/5

Answer 1

4 ( 1/4 ) y - ( 1 ( 7/12 ) y + ( 3/8 ) y ) = 4 ( 1/4 ) y - 1 ( 7/12 ) y - ( 3/8 ) y = 4 ( 6/24 ) y - 1 ( 14/24 ) y - ( 9/24 ) y = 3 ( 30/24 ) y - 1 ( 23/24 ) y = 2 ( 7/24 ) y ;
Y = 48
2 ( 7/24 ) * 48 = ( 55/24 ) * 48 = 55 * 2 = 110 ;
Y = 1 ( 3/5 ) = ( 8/5 )
( 55/24 ) * ( 8/5 ) = 11/3 = 3 ( 2/3 )
