\(\frac{254+399.253}{399.254-145}\)
\(=\frac{254+399.253}{399.\left(253+1\right)-145}\)
\(=\frac{254+399.253}{399.253+399.1-145}\)
\(=\frac{254+1}{1+399-145}=1\)
Chúc bạn học tốt!!!

254 x 399 - 145 / 254 + 399 x 253
= 254 x 399 - 154 / ( 253 + 1 ) x 399 + 254
= 254 x 399 + 399 - 154 / 254 x 399 + 254
= 253 + 399 x 254 / 254 + 399 x 254
= 1

a: 27,32 + 36,23 + 45,14 - 15,14 - 6,23 + 22,68
= ( 27,32 + 22,68 ) + ( 36,23 - 6,23 ) + (45,14 - 15,14)
= 50 + 30 + 30
=50 +60

254 + 399 x 253 / 399 x 254 - 145
= 399 x 253 +254 / 399 x 254 - 145
= 399 x 253 +254 / 399 x (254 + 1) - 145
= 399 x 253 +254 / 399 x 253 + 399 - 145
