\(\frac{9}{22}\)và \(\frac{3}{11}\)
Ta có : \(\frac{3}{11}=\frac{6}{22}\)
\(\frac{9}{22}+\frac{6}{22}=\frac{15}{22}\)
Ủng hộ nhé !
@nguyễn thị phương anh đây nhé :
\(\frac{12}{21}+\frac{11}{22}=\frac{264}{462}+\frac{231}{462}=\frac{495}{462}\)
\(\frac{9}{32}+\frac{35}{11}=\frac{99}{352}+\frac{1120}{352}=\frac{1219}{352}\)
\(\frac{12}{21}+\frac{11}{22}=\frac{4}{7}+\frac{1}{2}=\frac{8}{14}+\frac{7}{14}=\frac{15}{14}\)
\(\frac{9}{32}+\frac{35}{11}=\frac{99}{352}+\frac{1120}{352}=\frac{1219}{352}\)
\(\frac{9}{22}+\frac{3}{11}\)
\(=\frac{9}{22}+\frac{6}{22}\)
\(=\frac{15}{22}\)
Đáp số : \(\frac{15}{22}\)
\(\frac{9}{8}>\frac{8}{9}\)
\(\frac{16}{23}>\frac{16}{25}\)
\(\frac{8}{11}< \frac{8}{10}\)
\(\frac{10}{13}>\frac{19}{26}\)
\(\frac{13}{15}< \frac{11}{10}\)
\(\frac{11}{9}=\frac{44}{36}\)
9/8 > 8/9
16/23 > 16/25
8/11 < 8/10
10/13 > 19/26
13/15 < 11/10
11/9 = 44/36
Tham khảo nha !
Chúc bạn học giỏi !
