Rút gọn phân số:
\(\dfrac{143}{132}\) = ...
\(\dfrac{3535}{3737}\) = ...
`143/132=(143:11)/(132:11)=13/12`
`3535/3737=(3535:101)/(3737:101)=35/37`
a. \(\dfrac{13}{12}\)
b. \(\dfrac{35}{37}\)
Rút gọn số sau: -1515/-3131
\(\dfrac{-1515}{-3131}=\dfrac{\left(-1515\right):\left(-101\right)}{\left(-3131\right):\left(-101\right)}=\dfrac{15}{31}\)
rút gọn phân số 4242/3131 = .../...
`4242/3132=(4242:101)/(3131:101)=42/31`
\(\dfrac{4242}{3131}=\dfrac{4242:101}{3131:101}=\dfrac{42}{31}\)
\(\dfrac{4242}{3131}\)\(=\dfrac{4242:101}{3131:101}=\dfrac{42}{31}\)
Giúp toi
