Question

(13 1/6 - 2 2/13 * 2 10/21) * 1 5/47

Answer 1

$(13 frac{1}{6}-2 frac{2}{13} *2 frac{10}{21})*1 frac{5}{47}$
$1) 2 frac{2}{13} *2 frac{10}{21}= frac{28}{13}* frac{52}{21} = frac{208}{39}$
$2) 13 frac{1}{6} - frac{208}{39}= frac{79}{6}- frac{208}{39}= frac{ 79^{13}- 208^{2} }{78} = frac{1027-416}{78} = frac{611}{78}$
$3) frac{611}{78}*1 frac{5}{47}= frac{611}{78}* frac{52}{47} = frac{13*26}{39*1}= frac{338}{39}=8 frac{26}{39}$
