填空0.75 =( ):( )=(——) =( )% . 0.75 =( ): 12 = ( )% , 1 15 : 0 . 8化简为( ).
( ) ÷ 24 = 38 = 24 : ( )= ( )%.
(4) ( ) ÷8 = 21( ) =87.5%= 14 : ( )=( )= ( )64 .
(5) ( )% =(——)= 0.15 = ( ) : ( ).
填空0.75 =( ):( )=(——) =( )% . 0.75 =( ): 12 = ( )% , 1 15 : 0
填空0.75 =(75 ):(100 )=(75/100)=( 75)% .0.75 =( 9):12 = (75 )% ,115 :0 .8化简为( 575/4).( 912 ) ÷ 24 = 38 = 24 :( 0.63 )= ( 3800 )%.
(4) ( 7 ) ÷8 = 21( :24 ) =87.5%= 14 :( 16 )=( 0.875 )= ( 56/ )64 .
(5) ( 15 )% =(15/100)= 0.15 = ( 3 ) :( 20 ).
