Answer:

-3.5625

Step-by-step explanation:

You may be able to round your answer, I am not sure.

Step-by-step explanation:

3/8(0.4)-4.5

First, multiply 8 by 0.4 to get 3.2. Plug in that number to your new equation.

3/3.2-4.5

Now use order of operations (PEMDAS or GEMA) and divide 3 by 3.2.

0.9375-4.5

Subtract (Round that number if needed. If it says round your number, the answer will be different.)

Final Answer: -3.5625

ROUNDED TO THE NEAREST TENTH VERSION:

3/8(0.4)-4.5

First, multiply 8 by 0.4 to get 3.2. Plug in that number to your new equation.

3/3.2-4.5

Now use order of operations (PEMDAS or GEMA) and divide 3 by 3.2. (round to nearest tenth place.)

0.9-4.5

Now subtract

-3.6
