①496+250×16=496+250×4×4=496+4000=4496

② 31.25÷25×0.53=1.25×0.53=0.6625

③ 3.6÷(2.6+0.5)=3.6÷3.1≈1.16

④ 8.92×1.2-2.09=10.704-2.09=8.614

⑤ 425÷20+109×43=21.25+4687=4708.25

⑥ 3/7×(4/5-1/3)÷1/5=3/7×(12/15-5/15)×5=3/7×7/15×5=1

⑦ 5/8-(1/2+3/5)×5/11=5/8-11/10×5/11=5/8-1/2=1/8

⑧ 7/8÷9×3/5×35/72=7/8×1/9×3/5×72/35=3/25

祝你學習進步、幸福快樂!
