How do I simplify this equation?

Question

1/2( 5 - 36/4 ) + 30 divided by 6?

No silly/stupid answers. Please spare me.

Answer 1

1/2(5-9) + 30 by 4

= 28 / 4

= 7

Answer 2

Order of operations:

PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

1/2(5 - 36/4) + 30/6 (divide -36 by 4 and 30 by 6)

1/2(5 - 9) + 5 (subtract inside parentheses)

1/2(-4) + 5 (multiply)

-2 + 5 (add)

3 <===ANSWER

Answer 3

To start, break down the fraction given in the problem.

36/4 = 9.

So, 5 - 9 = -4.

Multiply that by the 1/2, and you get -2.

Now, there is a discrepancy in your question, so I will provide two different answers.

If the problem is asking for 30/6 + -2, then your answer is 5 - 2 = 3.

If the problem is asking for (30+ -2)/6, then your answer is 28/6 = 14/3.

Hope this helps at all!

Answer 4

MoonRose is right, remember your order of operations and you'll find these problems much easier to solve.  I assume your problem looks something like this:

½ (5 - 36/4) + 30

------------------------- =  First simplify the numerator.

6

½ (5 - 9) + 30

-------------------- =

6

½ (-4) + 30

---------------- =

6

-2 + 30

------------ =

6

28

---- =  Now factor the 28 and 6 Hint: 2/2=1

6

2(2)(7)

---------- =  

2(3)

2(7)

------ =  

3

14

------ =  Hint: 14 = 12+2 so 12/3 + 2/3 =
