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

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

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

Ai k mk k cho 3 k

Ai k mk k cho 3 k

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

ai k mk k cho 3 k

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

số cần tìm là:\(\frac{5}{1}+\frac{2}{1}=7\)

Ds:7

Số cần tìm là:

\(\frac{5}{1}+\frac{2}{1}\) = \(\frac{7}{1}\)

Đáp số: \(\frac{7}{1}\)

\(\frac{8}{15}+\frac{16}{30}+\frac{3}{5}+\frac{9}{10}+2\frac{3}{5}\)

\(=\frac{8}{15}+\frac{16}{30}+\frac{3}{5}+\frac{9}{10}+\frac{13}{5}\)

\(=\frac{16+16+18+27+78}{30}\)

\(=\frac{155}{30}\)

\(=\frac{31}{6}\)

Hc tốt #

\(\frac{8}{15}\)+\(\frac{16}{30}\)+\(\frac{3}{5}\)+\(\frac{9}{10}\)+2\(\frac{3}{5}\)

=\(\frac{16}{30}\)+\(\frac{16}{30}\)+\(\frac{18}{30}\)+\(\frac{27}{30}\)+\(\frac{13}{5}\)

=\(\frac{16+16+18+27}{30}\)+\(\frac{78}{30}\)

=\(\frac{77}{30}\)+\(\frac{78}{30}\)= \(\frac{155}{30}\)

 kết quả là 1

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