Question

(5/2-1/2):2+5/9×3/4

Answer 1

\(\left(\frac{5}{2}-\frac{1}{2}\right):2+\frac{5}{9}\times\frac{3}{4}\)

\(=\frac{4}{2}:2+\frac{5}{9}\times\frac{3}{4}\)

\(=1+\frac{5}{9}\times\frac{3}{4}\)

\(=1+\frac{15}{36}\)

\(=1+\frac{5}{12}\)

\(=\frac{17}{12}\)

Answer 2

\(\left(\dfrac{5}{2}-\dfrac{1}{2}\right):2+\dfrac{5}{9}\times\dfrac{3}{4}\\ =2:2+\dfrac{15}{36}\\ =1+\dfrac{5}{12}\\ =\dfrac{12}{12}+\dfrac{5}{12}\\ =\dfrac{17}{12}\)

Answer 3

(5/2-1/2):2+5/9×3/4 =2:2+5/9×3/4 =1+5/9×3/4 =1+5/12 =17/12 Mong bạn tick

Answer 4

\(\left(\frac{5}{2}-\frac{1}{2}\right)\div2+\frac{5}{9}\times\frac{3}{4}\)

\(=2\div2+\frac{5}{9}\times\frac{3}{4}\)

\(=1+\frac{5}{9}\times\frac{3}{4}\)

\(=1+\frac{5}{12}\)

\(=\frac{12}{12}+\frac{5}{12}=\frac{17}{12}\)
