Nguyễn Thị Thương Hoài · Accepted Answer

$\dfrac{111\times118-33}{112\times115+185}$

= $\dfrac{111\times\left(115+3\right)-33}{\left(111+1\right)\times115+185}$

= $\dfrac{111\times115+111\times3-33}{111\times115+115\times1+185}$

= $\dfrac{111\times115+333-33}{111\times115+115+185}$

= $\dfrac{111\times115+300}{111\times115+300}$

= 1Câu trả lời: $\dfrac{111\times118-33}{112\times115+185}$

= $\dfrac{111\times\left(115+3\right)-33}{\left(111+1\right)\times115+185}$

= $\dfrac{111\times115+111\times3-33}{111\times115+115\times1+185}$
