=( 65,27 - 55,27) + (25,3 + 214,7)
= 10 +( 25,3 + 214,7)
=10 + 240
= 250
25,3 - 55,27 + 214,7 + 65,27
= \(\left(25,3+214,7\right)+\left(65,27-55,27\right)\)
= 240 + 10
=205
= (25,3 + 214,7) + (-55,27 + 65,27)
= 240 + 10 = 250
25,3 - 55,27 + 214,7 +65,27
= ( 65,27 - 55,27 ) + ( 25,3 + 214,7 )
= 10 + ( 25,3 + 214,7 )
= 10 + 240
= 250
k mình nha!
