Ta có :
\(\frac{7}{10}+\frac{8}{10}+\frac{9}{10}+\frac{10}{10}\)
\(=\frac{7+8+9+10}{10}=\frac{34}{10}\)
Đap số : \(\frac{34}{10}\)
\(\frac{7}{10}+\frac{8}{10}+\frac{9}{10}+\frac{10}{10}=\frac{34}{10}\)
7/10 + 8/10 + 9/10 + 10/10
=15/10 + 9/10 + 10/10
=24/10 + 10/10
= 34/10
( hoặc ) 3,4
\(\frac{7}{10}+\frac{8}{10}+\frac{9}{10}+\frac{10}{10}=\frac{17}{5}\)
tíc mình nha
\(\frac{7}{10}+\frac{8}{10}+\frac{9}{10}+\frac{10}{10}=\frac{7+8+9+10}{10}=\frac{34}{10}=3,4\)
7/10+8/10+9/10+10/10
=7+8+9+10/10
=34/10
=3,4
