解答:解:①5.52-0.55-0.45,
=5.52-(0.55+0.45),
=5.52-1,
=4.52;
②12.59+4.37-2.59,
=12.59-2.59+4.37,
=10+4.37,
=14.37;
③36.5-36.5×0.95,
=36.5×(1-0.95),
=36.5×0.05,
=1.825;
④9.68-4.36+3.32-8.64,
=9.68+3.32-(4.36+8.64),
=13-13,
=0;
⑤2.4×1.02,
=2.4×1+2.4×0.02,
=2.4+0.048,
=2.448;
⑥8.6÷0.25÷4,
=8.6÷(0.25×4),
=8.6÷1,
=8.6;
⑦12.5×25×3.2,
=(12.5×8)×(25×0.4),
=100×10,
=1000;
⑧9.28×1.3+92.8×0.87,
=92.8×(0.13+0.87),
=92.8×1,
=92.8.
