\(5871:\left[928-\left(247-82.5\right)\right]\\ =5871:\left[928-\left(247-410\right)\right]\\ =5871:\left[928-\left(-163\right)\right]\\ =5871:1091\\ =\dfrac{5871}{1091}\)

5871/1091

\(=5871:\left[928-\left(247-410\right)\right]\)

\(=5871:\left(928+163\right)\)

\(=5871:1091\)

\(=\frac{5871}{1091}\)

tíc mình nha

247-410 sao chia được

5871⁰ : [928 - (247 - 82).5] + 2175⁰

= 1 : (928 - 165.5) + 1

= 1 : (928 - 825) + 1

= 1 : (-103) + 1

= 102/103

\(=5871:\left[928-165\cdot5\right]\\ =5871:\left[928-825\right]=5871:103=57\)

\(=5871:\left[928-165.5\right]=5871:\left[928-825\right]=5871:103=57\)
