 tính nhanh

e) \(\frac{0,1997+2,5\cdot12,5\cdot0,4\cdot0,08+0,8003}{1,25\cdot2,5\cdot8\cdot4}\)

g)\(\frac{\left(10,6524+0,3476\right)\cdot125\cdot0,4+8}{4\cdot0,1\cdot8\cdot0,25\cdot125}\)

Answer 1

e)\(\frac{0,1997+2,5\cdot12,5\cdot0,4\cdot0,08+8,003}{1,25\cdot2,5\cdot8\cdot4}=\frac{0,1997+1+8,003}{100}=\frac{2}{100}=\frac{1}{50}\)

g)\(\frac{\left(10,6524+0,3476\right)\cdot125\cdot0,4+8}{4\cdot0,1\cdot8\cdot0,25\cdot125}=\frac{11\cdot125\cdot0,4+8}{100}=\frac{558}{100}=5,58\)
