1. \(\frac{4}{3}\)= \(\frac{4x4}{3x4}\)=\(\frac{20}{12}\)
\(\frac{3}{4}\)=\(\frac{3x3}{4x3}\)=\(\frac{9}{12}\)
2.\(\frac{5}{4}\)=\(\frac{5x6}{4x6}\)=\(\frac{30}{24}\)
\(\frac{5}{6}\)=\(\frac{5x4}{6x4}\)=\(\frac{20}{24}\)
3.\(\frac{3}{8}\)=\(\frac{3x6}{8x6}\)=\(\frac{18}{48}\)
\(\frac{1}{6}\)=\(\frac{1x6}{6x8}\)=\(\frac{6}{48}\)
4.\(\frac{2}{5}\)=\(\frac{2x7}{5x7}\)=\(\frac{14}{35}\)
\(\frac{4}{7}\)=\(\frac{4x5}{7x5}\)=\(\frac{20}{35}\)
\(\frac{1}{4}=\frac{1x3}{4x3}=\frac{3}{12}\)
\(\frac{5}{6}=\frac{5x2}{6x2}=\frac{10}{12}\)
Chúc bạn học tốt.
😁😁😁
\(\frac{5}{6}=\frac{5\times4}{6\times4}=\frac{20}{24}\)
\(\frac{1}{4}=\frac{1\times6}{4\times6}=\frac{6}{24}\)
Vậy ....................
a: \(MSC:24\\ \dfrac{1}{3}=\dfrac{1\times8}{3\times8}=\dfrac{8}{24};\dfrac{1}{4}=\dfrac{1\times6}{4\times6}=\dfrac{6}{24}\)
b: \(MSC:24\\ \dfrac{5}{12}=\dfrac{5\times2}{12\times2}=\dfrac{10}{24};\dfrac{7}{6}=\dfrac{7\times4}{6\times4}=\dfrac{28}{24}\)
1. \(\dfrac{15}{10}=\dfrac{3}{2};\dfrac{18}{27}=\dfrac{2}{3};\dfrac{8}{100}=\dfrac{2}{25};\dfrac{2}{100}=\dfrac{1}{50}\)
2.\(MSC:36\\ \dfrac{1}{4}=\dfrac{1\times9}{4\times9}=\dfrac{9}{36};\dfrac{2}{9}=\dfrac{2\times4}{9\times4}=\dfrac{8}{36}\\ \\ MSC:6\\ \dfrac{5}{6};\dfrac{1}{3}=\dfrac{1\times2}{3\times2}=\dfrac{2}{6}\)
\(a,=\dfrac{15}{55};\dfrac{44}{55}\)
\(b,=\dfrac{7}{9};\dfrac{12}{9}\)
\(c=\dfrac{3}{6};\dfrac{2}{6};\dfrac{1}{6}\)
a. 15/55; 44/55
b. 7/9; 12/9
c. 3/6; 2/6; 1/6
a: 1/54=1/54
5/6=45/54
b: 3/22=3/22
6/11=12/22
c: 1/2=6/12
2/3=8/12
3/4=9/12
\(\frac{5}{6}=\frac{5}{6};\frac{1}{3}=\frac{3}{6}\)
\(\frac{1}{4}=\frac{10}{40};\frac{9}{10}=\frac{36}{40}\)
Mẫu số chung: 12
Ta có: \(\frac{5}{6}=\frac{10}{12}\)
\(\frac{1}{4}=\frac{3}{12}\)
