答

21/13

答

(3-112.5%+1又7分之1）x1又13分之8除以3又56分之1
=[(3-9/8+8/7)*21/13]/(169/56)
=(169/56)*21/13*56/169
=21/13

答

=(3-1.125+8/7)×(x1又13分之8)÷(169/56)
=(3-9/8+8/7)×(x1又13分之8)÷(169/56)
=(169/56)×(x1又13分之8)÷(169/56)
=x1又13分之8

答

(3-1-1/8+1+1/7)*(1+8/13)/(3+1/56)
=(3+1/56)*(1+8/13)/(3+1/56)
=1+8/13
=21/13
=1又8/13
