Help subtracting this mixed numbers 6 3/7-3 11/21

2 19/21 = 2.9048

Step-by-step explanation:

6    3/7   -    3   11/21    =    61/21

= 2  19/21

= 2.9047619

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
