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

5/8=1/2+1/8

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

b ai 1 :

cach 1 : 3/5=2/10+4/10

cach 2 :  3/5=3/10+3/10

cach 3 : 3/5=1/10+5/10

bai 2 : 1/2 = 3/10+2/10 ( bang 5/10 rut gon lai thi bang 1/2 nha)

bai 3 : ( mk lam ra tung buoc nha)

tong so truyen thieu nhi va sach giao khoa la:

1/2+1/5 = 7/10 ( truyen thieu nhi va SGK)

phan so chi cac loai sach con lai la :

1-7/10=3/10(cac loai sach con lai) (mk giai thik 1 tu dau ra luon nha 1 la toan bo sach trong thu vien)

Dap So : 3/10 cac loai sach con lai

bai 4:

7/8=1/2+1/4+1/8(1/2=4/8,1/4=2/8,1/8giu~ nguyen nha

vay 3 so 4/8+2/8+1/8=7/8 o day chi la mk giai thik thoy nha )

Dap So :  1/2+1/4+1/8

chuc ban hoc gioi va tot nha

a) \(7,\left(3\right)=7\frac{3}{9}=\frac{66}{9}=\frac{22}{3}\)

b) \(2,\left(34\right)=2\frac{34}{99}=\frac{232}{99}\)

c) \(0,\left(357\right)=\frac{357}{999}=\frac{119}{333}\)

d) \(1,2\left(3\right)=\frac{1}{10}.12,\left(3\right)=\frac{1}{10}.12\frac{3}{9}=\frac{1}{10}.\frac{37}{3}=\frac{37}{30}\)

cát phượng: Bạn thắc mắc số 1/10 trong bài của anh Việt ak !? Tớ giải thích giùm nhé.

\(\text{ 1,2(3) = 12(3): 10 }=\frac{12\left(3\right)}{10}=12\left(3\right)\cdot\frac{1}{10}\)

Thế này bạn đã hiểu chưa ?

5/8=1/8+1/2

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

C1:3/8+1/2

C2:1/8+1/2

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

2/3 = 4/6 = 1/6 + 3/6 = 1/6 + 1/2

\(\frac{2}{3}=\frac{4}{6}=\frac{1}{6}+\frac{3}{6}=\frac{1}{6}+\frac{1}{2}\)

tk đúng cho tớ nha

cảm ơn

Ta có:

2/3 

= 4/6

= 1/6 + 3/6

= 1/6 + 1/2

1/8+2/4=5/8

1/4+3/8

1/2+1/8

\(\frac{5}{8}=\frac{3}{16}+\frac{7}{16}=\frac{1}{16}+\frac{15}{16}=\frac{5}{16}+\frac{5}{16}\)

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