=204/217    41/49   95/100 nha bạn

204204/217217 = 204/217

414141/494949 = 41/49

171171171/180180180=171/180

đúng 100% luôn

tk mình nha bn

`4242/3132=(4242:101)/(3131:101)=42/31`

\(\dfrac{4242}{3131}=\dfrac{4242:101}{3131:101}=\dfrac{42}{31}\)

\(\dfrac{4242}{3131}\)\(=\dfrac{4242:101}{3131:101}=\dfrac{42}{31}\)

=15/31

\(\dfrac{-1515}{-3131}=\dfrac{\left(-1515\right):\left(-101\right)}{\left(-3131\right):\left(-101\right)}=\dfrac{15}{31}\)

tk mình nhé bạn

Thank you vẻy much
