Tính: 3+3/4
Giải thích
Lời giải
\(3 + \frac{3}{4} = \frac{{12}}{4} + \frac{3}{4} = \frac{{15}}{4}\) | \(\frac{2}{5} + 4 = \frac{2}{5} + \frac{{20}}{5} = \frac{{22}}{5}\) |
\(5 + \frac{6}{{14}} = 5 + \frac{3}{7} = \frac{{35}}{7} + \frac{3}{7} = \frac{{38}}{7}\) | \(\frac{9}{{15}} + 2 = \frac{3}{5} + 2 = \frac{3}{5} + \frac{{10}}{5} = \frac{{13}}{5}\) |
