Work: Calculate the value of equation (4×7×542×271+2×7×(440-2×(10+2×7))/2×538.5+7×440×563.5)/((4×7×542+2×7×(440-2×(10+2×7))/2+7×440)) .
Question type: Mathematical calculation
Solution:
(4×7×542×271+2×7×(440-2×(10+2×7))/2×538.5+7×440×563.5)/((4×7×542+2×7×(440-2×(10+2×7))/2+7×440))
=(4×7×542×271+2×7×(440-2×24)/2×538.5+7×440×563.5)/((4×7×542+2×7×(440-2×(10+2×7))/2+7×440))
=(4×7×542×271+2×7×392/2×538.5+7×440×563.5)/((4×7×542+2×7×(440-2×(10+2×7))/2+7×440))
=7325920/((4×7×542+2×7×(440-2×(10+2×7))/2+7×440))
=7325920/((4×7×542+2×7×(440-2×24)/2+7×440))
=7325920/((4×7×542+2×7×392/2+7×440))
=7325920/(21000)
=7325920/21000
=348.853333
Answer:(4×7×542×271+2×7×(440-2×(10+2×7))/2×538.5+7×440×563.5)/((4×7×542+2×7×(440-2×(10+2×7))/2+7×440))=348.853333
