Multiple Choice

Multiply and divide fractions. Assume all denominators are nonzero. $$\frac { t } { u } \text { and } \frac { v } { w }$$

A) $\frac { t + v } { u+ w } , \frac { t - w } { u - v }$
B) $\frac { t v } { u W } , \frac { t w } { u v }$
C) $\frac { t w } { v w } , \frac { t w } { w v }$
D) $\frac { u W } { t V } , \frac { u V } { t w }$
E) $\frac{t v}{u w}, \frac{u v}{t w}$
