First, you would add 4 to 4 and get 8.
Then, you would set up the proportion 8/52.
Simplify this proportion, which equals 2/13.
There is a 2 in 13 chance to draw a card that is a king or a queen from the deck.
48 since he eats 4 a minute and 4 times 12 equals 48.
Multiply each term by
b
and simplify.
a = cb
Rewrite the equation as
cb = a
Divide each term by
c
and simplify.
b = a/ c
Whats the model because 7/9 × 3/4= 7/12 which also equals to 21/36
as 7/12 is the simplified version of 21/36 but then for c 4×9 =36 so I'm a bit confused my self but here's a bit of a start
