Question

\(\frac{317\cdot452-201}{451\cdot317+116}\)

Giải giúp mình nha mình cần gấp lắm hôm nay phải có nha

Answer 1

\(\frac{317.452-201}{451.317+116}=\frac{317.\left(451+1\right)-201}{451.317+116}=\frac{317.451+317-201}{451.317+116}\)\(=\frac{451.317+\left(317-201\right)}{451.317+116}=\frac{451.317+116}{451.317+116}\)\(=1\)

Vậy: \(\frac{317.452-201}{451.317+116}=1\)

Answer 2

[317 x 452 - 201][451x317+116]=[317x(451+1)-201][451x317+116]

=[317x451+317-201][451x317+116]

=[317x451-116][451x317-116]=1

nhớ nhé!
