(4)已知△÷△=□△+△=○△-△=☆□+○+☆=11.4,那么:△=______.
(1)5.63×6.34+0.563×36.6,
=56.3×0.634+56.3×0.366,
=56.3×(0.634+0.366),
=56.3;
(2)1240×3.8+124×63-12.4×10,
=1240×3.8+1240×6.3-1240×0.1,
=1240×(3.8+6.3-0.1),
=1240×10,
=12400;
(3)

=
(4))□+〇+☆,
=△÷△+△+△+△-△,
=1+2△,
=11.4,
所以2△=10.4,因此△=5.2;
故答案为:56.3,12400,
,5.2.
=56.3×0.634+56.3×0.366,
=56.3×(0.634+0.366),
=56.3;
(2)1240×3.8+124×63-12.4×10,
=1240×3.8+1240×6.3-1240×0.1,
=1240×(3.8+6.3-0.1),
=1240×10,
=12400;
