3/4 + 5/6 = 9/12 + 10/12 = 19/12

Chúc bạn học tốt.

38/24 nhé

Bài 1:

a)\(\frac{12}{33}\)\(< \)\(\frac{16}{33}\)(So sánh tử)

b) \(\frac{2}{5}\)=\(\frac{4}{10}\)\(>\)\(\frac{3}{10}\)(Quy đồng mẫu, so sánh tử)

 Bài 2:

a)\(\frac{17}{24}+\frac{7}{24}=\frac{24}{24}=1\)

b) \(\frac{3}{5}+\frac{5}{3}=\frac{9}{15}+\frac{25}{15}=\frac{34}{15}\)

 Bài 3:

a)\(\frac{7}{4}-\frac{3}{4}=\frac{4}{4}=1\)

b)\(\frac{21}{24}-\frac{6}{8}=\frac{21}{24}-\frac{18}{24}=\frac{3}{24}=\frac{1}{8}\)

4/5 - 1/a = 3/10

        1/a = 4/5 - 3/10

        1/a = 1/2

           a = 1 : 1/2

           a = 2

Chúc bạn học tốt.

3 + 2/3 = 9/3 + 2/3 = 11/3

 trả lời hộ mình với\

Giúp mình với mình cần gấp lắm 

Ta có sơ đồ:

Dũng: | - - - - - | - - - - - | - - - - - | - - - - - | - - - - - | - - - - - | - - - - - |

Minh:  | - - - - - | - - - - - | - - - - - |                                                    Hiệu: 36 viên bi 

Số bi của Dũng là:

36 : (7 - 3) x 7 = 63 (viên)

Số bi của Minh là:

63 - 36 = 27 (viên)

Đáp số: Dũng: 63 viên bi;

             Minh: 27 viên bi.
