I NEED # help?

Question

i am bad at math can u please tell me how to solved these problems

(3 * -2) / ( 2 * -2 + 3*3 )

-3 * 5/6 / 1/6

/=divide 5/6 and 1/6 were fractions

3 * 1/5 / 5* -1/2

1/5 and -1/2 fraction

Answer 1

Here is real help. I hate all the other people who try to get free posts

Step by step:

1) (3 * -2) / ( 2 * -2 + 3*3 ) Do whatever is in top parenthesis first
-6/(2*-2 + 3*3) Do multiplication first then add
-6/(-4+9) Subtract 4 from 9
-6 / 5 is the answer

2)-3 * 5/6 / 1/6 - Firstdivide the fractions. To divide flip the second fraction and multiply.
-3 * (5/6 * 6/1) = -3 * (30/6) = -3* 5 = -15 is the answer

3)3 *1/5 /5 * -1/2 First, change /5 to * 1/5
3 * (1/5 * 1/5) *-1/2 = 3* (1/25) *-1/2 = 3*1/-50
=-3/50 is the answer

Also, please select a best answer. most of us are genuinely trying to help and it'd be nice if you'd return the favor.

Answer 2

3 * -2 = -6 ( because when you multiply or divide a positive number by a negative number, you get a negative number)
-6/ ( -4 +9) = -6/5 = -1 1/5 or -1.2

-5/2 / 1/6 = -( 5 * 6 ) / 2 ( because when you need to divide a fraction by a fraction all you need to do is swith the dividing fraction upside down) = -30/2 = -15

is the third one: ( 3*1/5) / ( 5 * -1/2) ? then:
3/5 / - 5/2 = - ( 3 * 2) / ( 5*5) = - 6/25 = - 0.24
or is it ( ( 3*1/5) / 5) * -1/2 ?
then 3/25 * -1/2 = -3/50 = -0.06

Answer 3

(3 * -2) / ( 2 * -2 + 3*3 )
= -6 / (-4 + 9) = -6/5


-3 * (5/6) / (1/6)
= -15/6 / (1/6)
=(-5/2) / (1/6)
=(-5/2) * (6/1)
=-30/2
= -15

3 * 1/5 / 5* -1/2
This one could depend on parentheses and order of operations, so check your problem
3 * (1/5) / 5* (-1/2)
=3/5 / 5 * (-1/2)
=3/25 * (-1/2)
= -3/50

I hope this helps!

Answer 4

Problem 1-
= (3 * -2) / ( 2 * -2 + 3*3 )
= (-6) / (-4 +9)
= (-6) / (5)
= -1.2
-----------------------------------------------------------------------
Problem 2-
= -3 * 5/6 / 1/6
= -3 * 5/6 * 6/1
= -3 * 5
= -15
-----------------------------------------------------------------------
Problem 3-

= 3 * 1/5 / 5* -1/2
= 3 * (1/5 / 5/1) * -1/2
= 3 * (1/25) * -1/2
= 3 * (1/25 * -1/2)
= 3 * (-1/50)
= 3 * -.02
= -.06

Hope this is what u require.

Answer 5

-30
-15
-1/150

i think that the third one might b wrong. hope that i helped

Answer 6

have you ever heard of PEMDAS
-Parenthaese
-Expoenents
-Multiplication
-Divison
-Addition
-Subtraction
hope that will help you!!

Answer 7

God how simple can you get!!!! it's :: E=MC2, hahahahaha
