$\frac{\frac{10}{11}}{\frac{3}{4}}=\frac{\frac{1}{4}}{\frac{1}{2}}$ false
numerator "is to" denominator... $\frac{\frac{10}{11}}{\frac{3}{4}}=\frac{\frac{1}{4}}{\frac{1}{2}}$ Cross multiply to determine if the proportion is true. $\frac{10}{11}\times\frac{1}{2}\overset?=\frac{3}{4}\times\frac{1}{4}$ $\frac{10}{22}\overset?=\frac{3}{16}$ $\frac{10\times8}{22\times8}\overset?=\frac{3\times11}{16\times11}$ $\frac{80}{176}\overset?=\frac{33}{176}\ X$
