Question

\(\frac{18}{37}\)+\(\frac{8}{24}\)+\(\frac{19}{37}\)-1\(\frac{23}{24}\)+\(\frac{2}{3}\)

(Mik làm rùi nhưng thấy sai sai nên đăng lên hỏi cho chắc^^)

Answer 1

\(\frac{18}{37}+\frac{8}{24}+\frac{19}{37}-1\frac{23}{24}+\frac{2}{3}\\ =\left(\frac{18}{37}+\frac{19}{37}\right)+\left(\frac{1}{3}+\frac{2}{3}\right)-1\frac{23}{24}\\ =1+1-1\frac{23}{24}\\ =2-1\frac{23}{24}\\ =\frac{1}{24}\)

Answer 2

\(\frac{18}{37}+\frac{8}{24}+\frac{19}{37}-1\frac{23}{24}+\frac{2}{3}\)

= \(\frac{18}{37}+\frac{8}{24}+\frac{19}{37}-\frac{47}{24}+\frac{16}{24}\)

= \(\left(\frac{18}{37}+\frac{19}{37}\right)+\left(\frac{8}{24}-\frac{47}{24}+\frac{16}{24}\right)\)

= \(1+\frac{-23}{24}\)

= \(\frac{24}{24}+\frac{-23}{24}\)

= \(\frac{1}{24}\)
