Question

3/6:4,9=?
13:0,65=?
18:45%=?
18:37,5%=?

Answer 1

$frac{3}{6} :4,9= frac{3}{6} : frac{49}{10}= frac{3}{6} * frac{10}{49}= frac{30}{294} = frac{5}{49}$

$13:0,65= frac{13}{1} :frac{65}{10}= frac{13}{1}* frac{10}{65}= frac{130}{65}=2$

$18:45=18:0,45=18: frac{45}{100}= frac{18}{1}* frac{100}{45} = frac{1800}{45} =40$

$18:37,5=18:0,375= frac{18}{1} : frac{375}{100}= frac{18}{1} * frac{100}{375} = frac{1800}{375}= frac{24}{5}=4 frac{4}{5}$
