When dealing with multiplications and divisions only, start calculating from left to right.
[tex]12\cdot(0.25)\cdot(-8)\div1/3\cdot5[/tex]Multiply 12 times (0.25):
[tex]3\cdot(-8)\div1/3\cdot5[/tex]Multiply 3 times -8:
[tex]-24\div1/3\cdot5[/tex]Notice that in the problem's procedure, the "-" sign was not included in the calculation.
Divide -24 by 1:
[tex]-24/3\cdot5[/tex]Divide -24 by 3:
[tex]-8\cdot5[/tex]Multiply -8 by 5:
[tex]-40[/tex]The final answer is -40.
