Question

Giúp mình nha:
1/2+2/5+6/9+5/8

Answer 1

\(1\frac{1}{2}+2\frac{1}{2}=\frac{3}{2}+\frac{5}{2}=\frac{8}{2}=\frac{4}{1}=4\)

Mấy đại ca làm ơn tick giùm em 8 cái em đang rất cần!!!

Answer 2

1\(\frac{1}{2}\)+2\(\frac{1}{2}\)=(1+2)+(\(\frac{1}{2}\)+\(\frac{1}{2}\))=3+1=4

Answer 3

\(1\frac{1}{2}+2\frac{1}{2}=\frac{3}{2}+\frac{5}{2}=\frac{8}{2}=\frac{4}{1}=4\)

Answer 4

\(1\frac{1}{2}+2\frac{1}{2}=1+\frac{1}{2}+2+\frac{1}{2}=1+2+\left(\frac{1}{2}+\frac{1}{2}\right)\)

\(=1+2+1=4\)

Answer 5

\(1\frac{1}{2}\)+ \(2\frac{1}{2}\)= \(\frac{3}{2}\)+ \(\frac{5}{2}\)= \(\frac{8}{2}\)= \(4\)

tick mình nha La Thi Hai Anh

Answer 6

4

Tik cho mk nha.............cảm ơn rất nhiều

Answer 7

1\(\frac{1}{2}\)+2\(\frac{1}{2}\)=\(\frac{3}{2}\)+\(\frac{5}{2}\)=\(\frac{3+5}{2}\)=\(\frac{8}{2}\)=4

Answer 8

1 1/2 + 2 1/2 = 3/2  + 5/2 = 8/2 = 4

Answer 9

thank you cac ban da tra loi cau hoi nay cua minh

Answer 10
