@`Meo`$\frac{15}{2}$ + $\frac{12}{2}$ + 5 + $\frac{3}{2}$= $\frac{15}{2}$ + $\frac{12}{2}$ + $\frac{3}{2}$ + 5= 15 + 5= 20 Bình luận
$\frac{15}{2}$ + $\frac{12}{2}$ + 5 + $\frac{3}{2}$ =$\frac{15}{2}$ + $\frac{12}{2}$ + $\frac{10}{2}$ + $\frac{3}{2}$ =$\frac{15 + 12 + 10 + 3}{2}$ =$\frac{40}{2}$ =20 Bình luận
@`Meo`
$\frac{15}{2}$ + $\frac{12}{2}$ + 5 + $\frac{3}{2}$
= $\frac{15}{2}$ + $\frac{12}{2}$ + $\frac{3}{2}$ + 5
= 15 + 5
= 20
$\frac{15}{2}$ + $\frac{12}{2}$ + 5 + $\frac{3}{2}$
=$\frac{15}{2}$ + $\frac{12}{2}$ + $\frac{10}{2}$ + $\frac{3}{2}$
=$\frac{15 + 12 + 10 + 3}{2}$
=$\frac{40}{2}$
=20
