Question

Tính giá trị biểu thức : A=5/2×2/3+1/3

Answer 1

\(A=\dfrac{5}{2}\times\dfrac{2}{3}+\dfrac{1}{3}\)

\(=\dfrac{5\times2}{2\times3}+\dfrac{1}{3}\)

\(=\dfrac{10}{6}+\dfrac{1}{3}\)

\(=\dfrac{5}{3}+\dfrac{1}{3}\)

\(=\dfrac{6}{3}\)

\(=2\)

Answer 2

` A = 5/2 xx 2/3 + 1/3 `

 

` A = (5/2 xx 2/3 ) + 1/3 `

 

` A = 5/3 + 1/3 `

 

` A = 6/3 `

 

` A = 2 `
