\(2+\frac{3}{8}=\frac{16}{8}+\frac{3}{8}=\frac{16+3}{8}=\frac{19}{8}\)
\(2\) +\(\frac{3}{8}\) = \(\frac{2}{1}\) + \(\frac{3}{8}\) = \(\frac{2x8}{1x8}\) + \(\frac{3x1}{8x1}\) = \(\frac{16}{8}\) + \(\frac{3}{8}\) \(\frac{16+3}{8}\) = \(\frac{19}{8}\)
\(2+\frac{3}{8}=\frac{16}{8}+\frac{3}{8}=\frac{16+3}{8}=\frac{19}{8}\)
\(2\) +\(\frac{3}{8}\) = \(\frac{2}{1}\) + \(\frac{3}{8}\) = \(\frac{2x8}{1x8}\) + \(\frac{3x1}{8x1}\) = \(\frac{16}{8}\) + \(\frac{3}{8}\) \(\frac{16+3}{8}\) = \(\frac{19}{8}\)

Lấy điểm hỏi đáp nè
ai đúng mình tick 3 tick nha
1+1+1+1+2+2+2+2+3+3+3+3+4+4+4+4+5+5+5+5+6+6+6+6+7+7+7+7+8+8+8+8+9+9+9+9=?
Hãy cho mình đáp án nhé ! yêu các bạn nhiều .
1+1+2+2+3+3+7+7+8+8+9+9=?
Tính nhẩm:
3 x 4 = 12 2 x 5 = 5 x 3 = 4 x 2 =
12 : 3 = 10 : 2 = 15 : 3 = 8 : 2 =
12 : 4 = 10 : 5 = 15 : 5 = 8 : 4 =
8 + 8 * 3 + 8 * 2 - 8 + 8 * 5
