Question

which statement is true?

A: $\frac{11}{20}$ = $\frac{4}{7}$
B: $\frac{11}{20}$ ≥ $\frac{4}{7}$
C: $\frac{11}{20}$ < $\frac{4}{7}$
D: $\frac{11}{20}$ > $\frac{4}{7}$

Answer 1

$\dfrac{11}{20}=\dfrac{11\cdot7}{20\cdot7}=\dfrac{77}{140}\\\\\dfrac{4}{7}=\dfrac{4\cdot20}{7\cdot20}=\dfrac{80}{140}\\\\\dfrac{77}{140} < \dfrac{80}{140}\to\dfrac{11}{20} < \dfrac{4}{7}\to\boxed{C.}$
