-3/8 divided by -9/10

 

Thanks, Hailey......here's a fractional answer...

 

(-3/8)  / (-9/10)  invert he second fraction and multiply

 

(-3/8) * ( 10 / -9)  swap denominators

 

(-3/-9) * ( 10/8)  =

 

(1/3) * (10/8)  =

 

10 / 24  =  

 

  5 / 12

Use what is known as Keep,  Change,  Flip.

 

Keep the first fraction,  change division to multiplication,  and flip the last fraction its reciprocal.

 

(-3/8) * (-10/9)

 

First off,  a negative times a negative is a positive,  so there is no need to keep the negatives in the expression,  really.

 

(3/8) * (10/9)

 

3 * 10 = 30

 

8 * 9 = 72

 

Simplify 30/72.  They are both divisible by 6.

 

30/6=5

 

72/6=12

 

Your final answer is 5/12.

 

I hope this helps!  @-Happy7
