\(\frac{7}{8}< 1< \frac{8}{7}\)
\(\Rightarrow\frac{7}{8}< \frac{8}{7}\)

12/3 > 11/14 vì 12/3 >1 và 11/14 < 1
19/20 < 39/38 vì 19/20 < 1 và 39/38 > 1
( k cho mình nha )
a) M điểm giữa của BC nên CM = MB
Tam giác ABM và tam giác ACM có : đáy CM = MB, chung đường cao tương ứng với đáy.
Nên S(ABM) = S(ACM)
b) S(ABC) = S(ABM) + S(ACM) mà S(ABM) = S(ACM)
Nên \(S\left(ABM\right)=\frac{1}{2}S\left(ABC\right)\)

Theo đề bài
\(\overline{abc,d}-\overline{a,bcd}=583,704\)
\(\Rightarrow100x\overline{a,bcd}-\overline{a,bcd}=583,704\)
\(\Rightarrow99x\overline{a,bcd}=583,704\Rightarrow\overline{a,bcd}=583,704:99=5,896\Rightarrow\overline{abc,d}=589,6\)
Tổng hai số là
\(\overline{589,6}+5,896=595,496\)
a=b pn nha đúng tk cho mk nha
A=B đúng tk cho mk nha
