\(\left(\frac{5}{13}-\frac{9}{14}\right)-\left(2+-\frac{21}{13}-\frac{5}{-14}\right)\)
\(=-\frac{47}{182}-\frac{135}{182}\)
\(=-1\)
tíc mình nha
(5/13 −9/14 )−(2+−21/13 −5/−14 )
=−47/182 −135/182
=−1
\(\left(\frac{5}{13}-\frac{9}{14}\right)-\left(2+\frac{-21}{13}-\frac{5}{-14}\right)\)
\(=\frac{5}{13}-\frac{9}{14}-2+\frac{21}{13}-\frac{5}{14}\)
\(=\left(\frac{5}{13}+\frac{21}{13}\right)+\left(-\frac{9}{14}+\frac{-5}{14}\right)-2\)
\(=2-1-2=-1\)
TÍNH NHANH
\(\frac{0,75-0,6+\frac{3}{7}+\frac{3}{13}}{2,75-2,2+\frac{11}{7}+\frac{11}{13}}\)
Ai nhanh và đúng đầu tiên tớ sẽ k
