\(=\frac{8}{4}\)\(=2\)

ai k mk mk k cho 3 k

\(\frac{5}{4}+\frac{3}{4}\)
\(=\frac{8}{4}\)
\(=2\)

\(\frac{2}{5}+\frac{3}{5}=\frac{5}{5}=1\)

\(\frac{2}{5}+\frac{3}{5}=1\)k mk nha

Số cần tìm là:

\(\frac{5}{2}\) x \(\frac{2}{3}\text{=}\frac{10}{6}\)

Đáp số: \(\frac{10}{6}\)

= 5/3 em nhé

\(\frac{5}{6}\)+\(\frac{7}{6}\)=\(\frac{12}{6}\)=2

ai k mk k cho 3 k

\(\frac{5}{6}\)+\(\frac{7}{6}\)=\(\frac{12}{6}\)=2

ai k mk k cho 3 k

=\(\frac{14}{7}\)ai k mk k lại 3 cái

=\(\frac{14}{7}\)ai k mk k lại 3 cái

 kết quả là 1

=\(\frac{5}{5}\)=1

ai k mk k cho 3 k

\(\frac{5}{6}+\frac{2}{6}=\frac{7}{6}\)

Ai k mk k cho 3 k

Ai k mk k cho 3 k

a ) \(\frac{5}{7}\) +     \(\frac{7}{14}\)

=   \(\frac{10}{14}\) +     \(\frac{7}{14}\)

= \(\frac{10+7}{14}\)= \(\frac{17}{14}\)

b ) \(\frac{5}{3}\) +    \(\frac{9}{12}\) +    \(\frac{8}{9}\)

= \(\frac{20}{12}\) +    \(\frac{9}{12}\) + \(\frac{8}{9}\)

=     \(\frac{29}{12}\) +  \(\frac{8}{9}\)

= \(\frac{357}{108}\)

A, \(=\frac{10}{14}+\frac{7}{14}\)

\(=\frac{17}{14}\)

B.\(=\frac{20}{12}+\frac{9}{12}+\frac{8}{9}\)

\(=\frac{29}{12}\)+\(\frac{8}{9}\)

\(=\frac{119}{36}\)

k mình nha
