\(\dfrac{5}{2}\times\dfrac{1}{3}+\dfrac{1}{4}\\ =\dfrac{5}{6}+\dfrac{1}{4}\\ =\dfrac{10}{12}+\dfrac{3}{12}\\ =\dfrac{13}{12}\)
= 5/6 + 1/4
= 10/12 + 3/12
= 13/12
Vậy giá trị biểu thức là 13/12
Nhân chia trc cộng trừ sau:
= 5/6 + 1/4
= 10/12 + 3/12
= 13/12
\(\dfrac{5}{2}\) x \(\dfrac{1}{3}\) + \(\dfrac{1}{4}\)
= \(\dfrac{6}{6}+\dfrac{1}{4}\)
= \(\dfrac{10}{12}+\dfrac{3}{12}\)
= \(\dfrac{13}{12}\)
5/6 + 1/4 = 20/24 + 6/24 = 26/24 = 13/12.
