.../84=2.016/...=.../56=252/336

Answer 1

1)
$\boxed{\frac{42}{15}}= \frac{3*42}{3*15}= \boxed{\frac{126}{45}}= \frac{126:9}{45:9}= \boxed{\frac{14}{5}}$

2)
$\frac{2*84}{2*300}= \boxed{\frac{168}{600}}= \frac{168:24}{600:24}= \boxed{\frac{7}{25}}= \frac{7*12}{25*12}= \boxed{\frac{84}{300}}= \frac{84*4}{300*4}= \boxed{\frac{336}{1200}}$

3)
$\frac{252:4}{336:4}= \boxed{\frac{63}{84}}= \frac{63*32}{84*32}= \boxed{\frac{2016}{2688}}= \frac{2016:48}{2688:48}= \boxed{\frac{42}{56}}= \frac{42*6}{56*6}= \boxed{\frac{252}{336}}$
