( 199+ 198/199 ) X (-5)
= ( 200 - 1/199 ) X (-5)
= -1000 + 5/199
= -999 -194/199
= -( 999 + 194/199 )
( 1/4 - 5/9 - 1/3 + 7/12 ) ÷ ( - 1/36 )
= ( 1/4 - 5/9 - 1/3 + 7/12 ) X ( -36 )
= -9 + 20 + 12 - 21
= 32 - 30
= 2
= ( 200 - 1/199 ) X (-5)
= -1000 + 5/199
= -999 -194/199
= -( 999 + 194/199 )
( 1/4 - 5/9 - 1/3 + 7/12 ) ÷ ( - 1/36 )
= ( 1/4 - 5/9 - 1/3 + 7/12 ) X ( -36 )
= -9 + 20 + 12 - 21
= 32 - 30
= 2
追答
-1^4 + (1+ 5/6) X (-3/11) ÷ ( 1/2 - 2 )"
= -1 + (11/6) X (-3/11) ÷ ( -3/2 )"
= -1 - 3/6 ÷ ( 9/4 )
= -1 - 1/2 X 4/9
= -1 - 2/9
= -( 11/9 )
-2" ÷ (-1/2)^4 X (-1)^2012 - ( 1+ 3/8 + 1+ 2/3 - 3 3/4 ) X 24
= -4 ÷ (1/16) X 1 - ( 3/8 + 2/3 - 1 - 3/4 ) X 24
= -4 X 16 - 9 - 16 + 24 + 18
= -89 + 42
= -47
