There are
of each suit in a deck of
cards.
This means the probability of drawing a diamond card is
. You can divide the numerator and denominator each by
to simplify. 
Since there are the same number of clubs as there are diamonds, the probabilities are the same.
This is a fraction equal to
7 yards ÷ 4 dresses
We want a unit rate where
<span>1 is in the denominator, </span>
so we divide top and bottom by 4.
7÷4= 1.75
_
4÷4=1.
Therefore, Kate used 1.75 yards per one dress (1.75 yds. p/ d)
