-2 x 3/12 x 5/10 x 7/15​

Answer 1

`\displaystyle\Large \boldsymbol -2 \cdot (3)/(12) \cdot (5)/(10) \cdot (7)/(15) =-2 \cdot (3 \!\!\!\!\diagup \cdot1)/(3 \!\!\!\!\diagup\cdot 4) \cdot (5 \!\!\!\!\diagup\cdot 1)/(5 \!\!\!\!\diagup\cdot 2) \cdot (7)/(15) =\\\\\\-(2 \!\!\!\!\diagup\cdot 7 )/(2 \!\!\!\!\diagup\cdot 4 \cdot 15) =\boxed{-(7)/(60)}`
