phân số đó có kết quả là 75/100 nhé!

sr lai nek

\(\frac{24}{32}=\frac{24:8}{32:8}=\frac{3}{4}=\frac{3\times25}{4\times25}=\frac{75}{100}\)

\(\frac{3}{6}\)= 3 : 6 = 0,5

\(\frac{24}{10}\)= 24 : 10 = 2,4

\(\frac{3}{6}\)\(=0,5\)

\(\frac{24}{10}\)\(=2,4\)

a) \(\frac{3}{6}=\frac{1}{2}=0,5\)

b) \(\frac{24}{10}=\frac{12}{5}=2,4\)

Em chỉnh lại cho câu hỏi đẹp hơn nha

1:

10 đơn vị và 35 phần nghìn=10,035

2: \(24\dfrac{4}{5}=24,8\)

3:

Chiều rộng là: \(200\cdot0.75=150\left(m\right)\)

Diện tích là \(200\cdot150=30000\left(m^2\right)=3\left(ha\right)\)

4:

\(\overline{a,bcd}\)

a có 4 cách chọn

b có 3 cách chọn

c có 2 cách chọn

d có 1 cách chọn

Do đó: 4*3*2*1=24 cách

\(\dfrac{13}{2}=\dfrac{13x5}{2x5}=\dfrac{65}{10}\)

\(\dfrac{11}{40}=\dfrac{11x25}{40x25}=\dfrac{275}{1000}\)

\(\dfrac{32}{5}=\dfrac{32x2}{5x2}=\dfrac{64}{10}\)

\(\dfrac{21}{250}=\dfrac{21x4}{250x4}=\dfrac{84}{1000}\)

\(\dfrac{1}{200}=\dfrac{1x5}{200x5}=\dfrac{5}{1000}\)

giúp mình với

câu 1 của bạn viết tiếu gì ko đấy alo!

Đề sai rồi bạn

\(\frac{13}{2}\)\(=\frac{65}{10}\)\(=6,5\)

\(\frac{11}{40}\)\(=\frac{11x25}{40x25}\)\(=\frac{275}{1000}\)\(=0,275\)

\(\frac{32}{5}\)\(=\frac{64}{10}\)\(=6,4\)

\(\frac{21}{250}\)\(=\frac{84}{1000}\)\(=0,084\)

\(\frac{1}{200}\)\(=\frac{5}{1000}\)\(=0,005\)

\(\frac{1}{2}=\frac{1\times5}{2\times5}=\frac{5}{10}\)

\(\frac{49}{140}=\frac{49:7}{140:7}=\frac{7}{20}=\frac{7\times5}{20\times5}=\frac{35}{100}\)

\(\frac{36}{600}=\frac{36:6}{600:6}=\frac{6}{100}\)

\(\frac{12}{24}=\frac{12\times5}{24\times5}=\frac{60}{100}\)
