    Giải đáp+Lời giải và giải thích chi tiết:
    $23\dfrac{1}{4}.$$\dfrac{7}{5}-13$$\dfrac{1}{4}:$$\dfrac{5}{7}$
    $=23\dfrac{1}{4}.$$\dfrac{7}{5}-13$$\dfrac{1}{4}.$$\dfrac{7}{5}$
    $=\dfrac{7}{5}.(23$$\dfrac{1}{4}-13$$\dfrac{1}{4})$
    $=\dfrac{7}{5}.10$
    $=\dfrac{70}{5}$
    $\text{=14}$
    $\text{#mct}$

    23$\dfrac{1}{4}$ . $\dfrac{7}{5}$ – 13$\dfrac{1}{4}$ : $\dfrac{5}{7}$
    = 23$\dfrac{1}{4}$ . $\dfrac{7}{5}$ – 13$\dfrac{1}{4}$ . $\dfrac{7}{5}$
    = $\dfrac{7}{5}$ . (23$\dfrac{1}{4}$ – 13$\dfrac{1}{4}$)
    $\text{= $\dfrac{7}{5}$ . 10}$
    $\text{= $\dfrac{70}{5}$}$
    $\text{= 14}$
