Alice evaluated the expression below but got an incorrect answer.12 · (0.25) · (-8) ÷ 1/3 · 53 · (8) ÷ 1/3 · 524 · 1/3 · 58 · 5 40Find and describe Alices error(s)Find the correct value of the expression.

Respuesta :

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.
