mọi người làm rõ ra hộ em nha

a  4/6+27/81=1

b  48/96-135/270=0

c  30303/80808+30303/484848=7/16

a) = 1

b) = 0

c) = 7/16

\(\frac{4}{6}+\frac{27}{81}\)

\(=\frac{2}{3}+\frac{1}{3}\)

\(=\frac{3}{3}\)

\(=1\)

=3/8+5/8=1

Ta có :

\(\dfrac{30303}{80808}=\dfrac{30303:10101}{80808:10101}=\dfrac{3}{8}\)

\(\dfrac{303030}{484848}=\dfrac{303030:10101}{484848:10101}=\dfrac{30}{48}=\dfrac{5}{8}\)

Vậy :

\(\dfrac{30303}{80808}+\dfrac{303030}{484848}=\dfrac{3}{8}+\dfrac{5}{8}=1\)

=1 nhé bạn

\(\dfrac{48}{96}-\dfrac{135}{270}\)

\(=\dfrac{48:48}{96:48}-\dfrac{135:135}{270:135}\)

\(=\dfrac{1}{2}-\dfrac{1}{2}\)

\(=0\)

3/8+5/8=1

=\(\dfrac{3}{8}\)+\(\dfrac{3}{4}\)=\(\dfrac{3}{8}\)+\(\dfrac{6}{8}\)=\(\dfrac{9}{8}\)

=3/8+5/8=1

1) ???

2)

a, \(\frac{-22}{55}=\frac{-22:11}{55:11}=\frac{-2}{5}\)

\(\frac{-26}{65}=\frac{-26:13}{65:13}=\frac{-2}{5}\)

=> ĐPCM

b, \(\frac{114}{122}=\frac{114:2}{122:2}=\frac{57}{61}\)

\(\frac{5757}{6161}=\frac{5757:101}{6161:101}=\frac{57}{61}\)

=> ĐOCM

3)

\(\frac{30303}{80808}+\frac{303030}{484848}=\frac{15}{4}+\frac{5}{8}=\frac{30+5}{8}=\frac{35}{8}\)

~ Ủng hộ nha ae ~

1, \(\frac{5}{-7}=\frac{-5}{7}=\)\(\frac{-10}{14}\)

2, a, \(\frac{-22}{55}=\frac{-26}{65}\)vì \(-22.65=-26.55=-1430\)

    b,\(\frac{114}{122}=\frac{5757}{6161}\)vì \(114.6161=122.5757=702354\)

3,\(\frac{30303}{80808}+\frac{303030}{484848}=\frac{3}{8}+\frac{5}{8}=1\)

\(\frac{30303}{80808}+\frac{303030}{484848}=1\)

Hk tốt

  \(\frac{30303}{80808}+\frac{303030}{484848}\)

\(=\frac{3}{8}+\frac{5}{8}\)

\(=\frac{8}{8}\)

\(=1\)

\(\frac{30303}{80808}\)\(+\frac{303030}{484848}\)\(=\frac{39179597184}{39179597184}\)\(=1\)
