Question

1/2,5/6 và 3/10 1/2,12/8,5/24 Quy đồng ms các phân số

Answer 1

\(\dfrac{1}{2}=\dfrac{30}{60};\dfrac{5}{6}=\dfrac{50}{60};\dfrac{3}{10}=\dfrac{18}{60}\)

\(\dfrac{1}{2}=\dfrac{12}{24};\dfrac{12}{8}=\dfrac{36}{24};\dfrac{5}{24}=\dfrac{5}{24}\)

Answer 2

\(MSC:60\\ \dfrac{1}{2}=\dfrac{1\times30}{2\times30}=\dfrac{30}{60}\\ \dfrac{5}{6}=\dfrac{5\times10}{6\times10}=\dfrac{50}{60}\\ \dfrac{3}{10}=\dfrac{3\times6}{10\times6}=\dfrac{18}{60}\)

Vậy ta quy đồng các số `1/2;5/6;3/10` ta được `30/60;50/60;18/60`

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

\(MSC:24\\ \dfrac{1}{2}=\dfrac{1\times12}{2\times12}=\dfrac{12}{24}\\ \dfrac{12}{8}=\dfrac{12\times3}{8\times3}=\dfrac{36}{24}\\ \dfrac{5}{24}=\dfrac{5}{24}\)

Vậy ta quy đồng các số `1/2;12/8;5/24` ta được `12/24;36/24;5/24`
