Bạn ơi hình như bạn viết sai đề bài rồi

không đâu Nguyễn Bảo ngọc , mình viết đúng mà

Bài 3:

Chiều rộng là:

\(\dfrac{11}{4}-\dfrac{3}{2}=\dfrac{11}{4}-\dfrac{6}{4}=\dfrac{5}{4}\left(m\right)\)

Chu vi là:

\(\left(\dfrac{11}{4}+\dfrac{5}{4}\right)\cdot2=\dfrac{16}{4}\cdot2=4\cdot2=8\left(m\right)\)

Diện tích là:

\(\dfrac{11}{4}\cdot\dfrac{5}{4}=\dfrac{55}{16}\left(m^2\right)\)

bài 1 :

a) \(3\dfrac{4}{5}\)= \(\dfrac{19}{5}\)                                   b) \(4\dfrac{3}{5}\)=\(\dfrac{23}{5}\)

c) \(11\dfrac{12}{13}\)= \(\dfrac{155}{13}\)                              d) 12 \(\dfrac{11}{13}\)= \(\dfrac{167}{13}\)

bài 1
a)
\(3\dfrac{4}{5}=\dfrac{3x5+4}{5}=\dfrac{19}{5}\)
b)
\(4\dfrac{3}{5}=\dfrac{4x5+3}{5}=\dfrac{23}{5}\)
c)
\(11\dfrac{12}{13}=\dfrac{11x13+12}{13}=\dfrac{155}{13}\)
d)
\(12\dfrac{11}{13}=\dfrac{12x13+11}{13}=\dfrac{167}{13}\)
bài 2
a)\(3\dfrac{3}{4}+1\dfrac{1}{2}=\dfrac{3x4+3}{4}+\dfrac{1x2+1}{2}=\dfrac{15}{4}+\dfrac{3}{2}=\dfrac{21}{4}\)
b)\(3\dfrac{3}{4}-1\dfrac{1}{2}=\dfrac{15}{4}-\dfrac{3}{2}=\dfrac{15}{4}-\dfrac{6}{4}=\dfrac{9}{4}\)
c)\(3\dfrac{3}{4}x1\dfrac{1}{2}=\dfrac{15}{4}x\dfrac{3}{2}=\dfrac{45}{8}\)
d)\(3\dfrac{3}{4}:1\dfrac{1}{2}=\dfrac{15}{4}:\dfrac{3}{2}=\dfrac{15}{4}.\dfrac{2}{3}=\dfrac{5}{2}\)

3/4=0,75
=> 0,6<3/4
