[tex]\frac{ 64 }{ \frac{ \frac{ \frac{ \frac{ 5 }{ 2.6 } }{ 25 } }{ 2 } }{ 4 } } = \frac{64\times 4}{\frac{\frac{\frac{5}{2.6}}{25}}{2}} = \frac{256}{\frac{\frac{\frac{5}{2.6}}{25}}{2}} = \frac{256}{\frac{\frac{5}{2.6}}{25\times 2}} = \frac{256}{\frac{\frac{50}{26}}{25\times 2}} = \frac{256}{\frac{\frac{25}{13}}{25\times 2}} = \frac{256}{\frac{\frac{25}{13}}{50}} = \frac{256}{\frac{25}{13\times 50}} = \frac{256}{\frac{25}{650}} = \frac{256}{\frac{1}{26}} = 256\times 26 = 6656 [/tex]
