5871⁰ : [928 - (247 - 82).5] + 2175⁰
= 1 : (928 - 165.5) + 1
= 1 : (928 - 825) + 1
= 1 : (-103) + 1
= 102/103
\(5871:\left[928-\left(247-82.5\right)\right]\\ =5871:\left[928-\left(247-410\right)\right]\\ =5871:\left[928-\left(-163\right)\right]\\ =5871:1091\\ =\dfrac{5871}{1091}\)
\(=\dfrac{5871}{928-\left(247-410\right)}=\dfrac{5871}{928-247+410}\)
\(=\dfrac{5871}{1091}\)
\(5871:\left[928-\left(247-82\cdot5\right)\right]\)
\(=5871:\left[928-\left(247-410\right)\right]\)
\(=5871:\left(928+163\right)\)
