-5 2/7 divided by -2 1/7
sasho [114]
First convert to an improper fraction:
-5 2/7 = -37/7
-2 1/7 = -15/7
So now you have -37/7 / -15/7
When you divide with a fraction, you just flip the numerator and denominator of the divisor and multiply instead, so
-37/7 * -7/15 = 37/15 which would be in "improper" form.
To convert it to mixed number form it would be 2 7/15

scoundrel [369]

Answer:

Width  = 50ft

Length = 160ft

Step-by-step explanation:

Given parameter:

The perimeter of the flag is 420ft

Unknown:

Length of flag  = ?

Width of flag  = ?

Solution:

To solve this problem;

 Perimeter of the flag is given as:

  Perimeter  = 2(Length + width)

Length  =110 + Width

  Now insert the parameters:

     420  = 2(110 + Width + Width )

   let w = width

     420  = 2(110 + 2w)

     420  = 220 + 4w    

      4w  = 200

         w  = 50ft

Length  = 110 + 50 = 160ft
