HELP ME
\(\frac{19.4-95}{19.3+76}=\frac{19.4-19.5}{19.3+19.4}=\frac{19\left(4-5\right)}{19\left(3+4\right)}=\frac{-1}{7}\)
\(19\times4-\frac{95}{19}\times3+76\)
\(=76-\frac{285}{19}+76\)
\(=\left(76-76\right)+\frac{285}{19}\)
\(=0+\frac{285}{19}=\frac{285}{19}\)
19 x 4 - 95/19 x 3 +76
=19 x 4 - 19 x 5/19 x 3 + 19 x 4
= 19(4 - 5)/19(3 + 4)
= 19(-1)/19 x 7
(19 với 19 ta rút gọn)
= -1/7
k cho mik nhé :)
