Answer 1

$frac{56}{91} = frac{8}{13}$

$frac{65}{125} = frac{13}{25}$

$frac{121}{165} = frac{11}{15}$

$frac{16cdot10cdot18}{70cdot12cdot24} = frac{1}{7}$

$frac{15cdot35cdot21}{75cdot49cdot14} = frac{3}{14}$

$frac{8cdot7+5cdot7-2cdot7}{121} = frac{7(8+5-2)}{121} = frac{7}{11}$

$1260=2^2cdot3^2cdot5cdot7 \ 1980=2^2cdot3^2cdot5cdot11 \ HOD=2^2cdot3^2cdot5=180 \ frac{1260}{1980} = frac{7}{11}$
