Answer:

Recipe 1 used
1(7)/(9) times as many cups and
1(1)/(6) more cups than Recipe 2.

Explanation:

By subtraction:

2
(2)/(3) - 1
(1)/(2)


(8)/(3) -
(3)/(2)


(8*2)/(3*2) -
(3*3)/(2*3)


(16)/(6)-(9)/(6) = (7)/(6) =1(1)/(6) cups more

By division:

2
(2)/(3) / 1
(1)/(2)


(8)/(3) /
(3)/(2)


(8)/(3) *
(2)/(3)


(8*2)/(3*3)=(16)/(9) =1(7)/(9) times as many cups more
