Question

4/5(720-240)-180 step by step

Answer 1

To solve, we use the order of operations PEMDAS, where

P = Parenthesis

E = Exponets

M = Multiplication

D = Division

A = Addition

S = Subtraction

State the expression to be simplified:

Possibility 1

`(4)/(5)(720-240)-180`

Expanding the parenthesis:

`(4)/(5)*480-180`

Multiplying then subtracting,

`384-180`

Therefore, the answer is 204.

Possibility 2

`(4)/(5(720-240))-180`

Expanding parenthesis:

`(4)/(5*480)-180`

Multiplying:

`(4)/(2400)-180`

Dividing then subtracting:

`\begin{gathered} (1)/(600)-180 \\ =-179.998 \end{gathered}`

Therefore, the answer is -179.998.

Possibility 3

`(4)/(5(720-240)-180)`

Expanding parenthesis:

`(4)/(5*480-180)`

Multiplying:

`(4)/((2400-180))`

Further expanding the parenthesis then dividing:

`\begin{gathered} (4)/(2220) \\ =0.0018 \end{gathered}`

Therefore, the answer is 0.0018.
