95×125+125×14-25×5

777×9/10+37×11又1/10

[(4.5-3又2/3)÷1又6/7]×(1又4/7×1.5+1又5/14)

(5.04-1又3/8-0.625-2又1/25)÷(1又1/8-0.125)

95×125+125×14-25×5
=125(95+14-1)=13500

777×9/10+37×11又1/10 =111*63/10+37*111/10
=111(63+37)/10=1110

[(4.5-3又2/3)÷1又6/7]×(1又4/7×1.5+1又5/14)
=(9/2-11/3)*7/13*(11/7*3/2+19/14)
=(9/2-11/3)*(33/26+19/26)
=9-22/3=1又2/3

(5.04-1又3/8-0.625-2又1/25)÷(1又1/8-0.125)
=(5.04-11/8-0.625-51/25)÷(9/8-1/8)
=75/25-(11/8+5/8)=1

1:125×(95+14)-125
=125×(109-1)
=125×108
=13500
