A) $\frac { 144 } { 49 } \mathrm { t }$
B)t
C) $\frac { 193 } { 84 } \mathrm { t }$
D) $\frac { 7 } { 12 } \mathrm { t }$

Question

Quizplus · Accepted Answer

The expression simplifies to $t$ because $\frac { 12 } { 7 } \times \frac { 7 } { 12 } = 1$, and multiplying $t$ by 1 leaves $t$ unchanged.
