- Ý kiến trên là sai bởi vì trẻ em ngoài quyền học tập thì còn có những trách nhiệm, nghĩa vụ khác phải làm, đó là bổn phận của trẻ em đối với bản thân và gia đình 

ví dụ:

- nghĩa vụ giúp đỡ gia đình, bố mẹ làm việc nhà.

- thực hiện tốt các quyền trẻ em của mình và của người khác.

- bảo vệ môi trường, bảo vệ an ninh xã hội...

- Kính trọng ông bà, cha mẹ, người lớn.

a) Tỉ số phần trăm của 30 m so với 70 m là:

     \(\dfrac{30\cdot100}{70}\%\approx42,9\%\)

Vậy tỉ số phần trăm của 30 m so với 70 m ≈ 42,9 %

b) Số học sinh khối 6 của trường đó là:

      86 : 40% = 215 ( học sinh )

Vậy số học sinh khối 6 của trường đó là 215 học sinh.

tỉ số phần trăm của kết quả làm tròn là 30 nhân 70 chia 100 ok

tôi mới học lớp 5 thôi mà trả lời được toán lớp 6 đó nhoa

Giỡn thôi, tôi làm sai rồi

\(32^{-n}\cdot16^n=1024\)

=>\(2^{-5n}\cdot2^{4n}=1024\)

=>\(2^{-n}=2^{10}\)

=>-n=10

=>n=-10(loại)

Vậy: \(n\in\varnothing\)

\(H=\dfrac{1}{6}+\dfrac{1}{12}+\dfrac{1}{20}+\dfrac{1}{30}+\dfrac{1}{42}+\dfrac{1}{72}+\dfrac{1}{90}\)

\(H=\dfrac{1}{90}+\left(\dfrac{1}{6}+\dfrac{1}{12}+\dfrac{1}{20}+\dfrac{1}{30}+\dfrac{1}{42}+\dfrac{1}{72}\right)\)

\(H=\dfrac{1}{90}+\left(\dfrac{1}{2.3}+\dfrac{1}{3.4}+\dfrac{1}{4.5}+\dfrac{1}{5.6}+\dfrac{1}{6.7}+\dfrac{1}{7.8}\right)\)

\(H=\dfrac{1}{90}+\left(\dfrac{1}{2}-\dfrac{1}{3}+\dfrac{1}{3}-\dfrac{1}{4}+\dfrac{1}{4}-\dfrac{1}{5}+\dfrac{1}{5}-\dfrac{1}{6}+\dfrac{1}{6}-\dfrac{1}{7}+\dfrac{1}{7}-\dfrac{1}{8}\right)\)

\(H=\dfrac{1}{90}+\left(\dfrac{1}{2}-\dfrac{1}{8}\right)\)

\(H=\dfrac{1}{90}+\left(\dfrac{4}{8}-\dfrac{1}{8}\right)\)

\(H=\dfrac{1}{90}+\dfrac{3}{8}\)

\(H=\dfrac{49}{360}\)
