Question

Rút gọn các phân số sau để được phân số tối giản :

a, 30/48

b, -104/182

Answer 1

a, 30/48=5/8

b, -104/182= -4/7

Answer 2

a, 30/48 = 5/8

b, -104/182=-4/7

Answer 3

1)

\(a.\frac{30}{48}=\frac{30:6}{48:6}=\frac{5}{8}\)

\(b.\frac{-104}{182}=\frac{-104:2}{182:2}=\frac{-52}{91}\)

Answer 4

a, \(\frac{30}{48}\)= \(\frac{5}{8}\)

b, - \(\frac{104}{182}\)= \(\frac{-52}{91}\)

Answer 5

\(a)\) \(\frac{30}{48}=\frac{30:6}{48:6}=\frac{5}{8}\)

\(b) \) \(\frac{-104}{182}=\frac{-104:26}{182:26}=\frac{-4}{7}\)
