Question

thực hiện phép tính (hợp lí nếu có thể)

Answer 1

d: =1/2+3/4-3/4+4/5

=1/2+4/5=5/10+8/10=13/10

h: \(=\dfrac{37}{7}\left(\dfrac{8}{11}+\dfrac{5}{11}-\dfrac{2}{11}\right)=\dfrac{37}{7}\)

m: \(=\left(-\dfrac{4}{13}-\dfrac{9}{13}\right)+\left(\dfrac{3}{4}+\dfrac{1}{4}\right)+\dfrac{5}{17}=\dfrac{5}{17}\)
