下列哪个选项等于\( \frac{11}{56} \div \frac{7}{8} ? \)
a) \( \frac{11}{64} \)
b) \( \frac{11}{49} \)
c) \( \frac{49}{11} \)
d) \( \frac{64}{11} \)
已知: $\frac{11}{56} \ \div \ \frac{7}{8}$
求解: 我们需要求$\frac{11}{56} \ \div \ \frac{7}{8}$的值
解: $\frac{11}{56} \ \div \ \frac{7}{8}$
= $\frac{11}{56} \ \times \ \frac{8}{7} \ =\ \frac{11}{49}$
