5 * 2 1/5=?
4 2/7 * 2=?
2 2/25 * 1 9/16=?
13/43 * 8 7/26=?
Помогите, пожалуйста!

$5*2 frac{1}{5}=5* frac{11}{5}=11$

$2 frac{2}{25}*1 frac{9}{16}= frac{52}{25}* frac{25}{16}= frac{52}{16}= frac{13}{4}=3 frac{1}{4}$

$4 frac{2}{7}*2= frac{16}{7}*2= frac{32}{7} =4frac{4}{7}$

$frac{13}{43}*8 frac{7}{26}= frac{13}{43}* frac{208}{26}= frac{104}{43} =2 frac{18}{43}$
