Приведите к общему знаменателю дробей: а) 3/8 и 5/9 б) 4/48 и 5/96 в) 8/30 и 6/35
"/" - это дробь

Answer 1

$\frac{3}{8} = \frac{3*9}{8*9} = \frac{27}{72} \\ \\ \frac{5}{9} = \frac{5*8}{9*8} = \frac{40}{72} \\ \\ \frac{4}{48} = \frac{4*2}{48*2} = \frac{8}{96} \\ \\ \frac{5}{96} = \frac{5*1}{96*1} = \frac{5}{96} \\ \\ \frac{8}{30} = \frac{8*7}{30*7} = \frac{56}{210} \\ \\ \frac{6}{35} = \frac{6*6}{35*6} = \frac{36}{210}$
