Question

qual o valor da expressão2 1/2 + 3/2 x 1/2

Answer 1

1/2 + 3/2 x 1/2
= 1/2 + (3 x 1)/(2 x 2)
= 1/2 + 3/4
= (1 x 2)/(2 x 2) + 3/4
= 2/4 + 3/4
= 5/4

Answer 2

fica assim:
1/2 + 3/2 x 1/2
1/2 + (3 x 1)/(2 x 2)
1/2 + 3/4
(1 x 2)/(2 x 2) + 3/4
2/4 + 3/4
= 5/4
seu valor é$\left[\begin{array}{ccc}&&\\5/4&&\\&&\end{array}\right]$
