Answer:
-(5)/(12)

Steps:


1(1)/(4)* \left(-1\right)(1)/(3)

Convert mixed numbers to improper fractions:
1(1)/(4)
=(5)/(4)


=(5)/(4)* \left(-1\right)(1)/(3)


\mathrm{Apply\:the\:rule}:\quad \:a\left(-b\right)=-ab


(5)/(4)\left(-1\right)=-(5)/(4)* \:1


=-(5)/(4)* \:1* (1)/(3)


\mathrm{Apply\:rule}\:a* 1=a


=-(5)/(4)* (1)/(3)


\mathrm{Apply\:the\:fraction\:rule}:\quad (a)/(b)* (c)/(d)=(a\:* \:c)/(b\:* \:d)


(5)/(4)* (1)/(3)=(5* \:1)/(4* \:3)


=-(5* \:1)/(4* \:3)


\mathrm{Multiply\:the\:numbers:}\:5* \:1=5


=-(5)/(4* \:3)


\mathrm{Multiply\:the\:numbers:}\:4* \:3=12


=-(5)/(12)

Hope This Helps!
