I really need help with my home ......?

Question

im a freshman and i need help with man im in a algebra 1 class and it is real hard this are some of my problems=

4 over 5 divided by minus (8over5) how do you do that

Answer 1

4

--- <== Over

5

------------------

- 8

------

~5

I think that's how it goes i hope...

First do the reciprocal of -8/5 = -5/8

Now change the division sign to multiplication...

4/5 * -5/8

Find a common denominator.

Multiply both denominators 5*8 = 40

Now 40 is going to be your denominator for both fractions next Multiply 4 & 8 = 32/40

Now -5 * 5 = -25/40

32/40 * -25/40

Multiply straight across.

32 * -25

-----------

40 * 40

-800

------

1600

Reduces to

-1/2 <== That's your answer!!

Hope this helped!! :]

Answer 2

I'm pretty sure that to divide fractions you need to change the problem to multiplication and invert the second fraction.. in other words..

  4/5 / -8/5

= 4/5 * -5/8

and solve from there

Answer 3

4/5 divided by negative 5/8 = negative 1/2

Here's how you do it:

STEP 1: 4/5 (division symbol) (-8/5)

STEP 2: 4/5 (multiplication symbol or dot) (-5/8)

STEP 3: Cancel the fives and you get -4/8

STEP 4: Simplify -4/8 to -1/2

Hope this helped

I'm positive this is the right answer
