Answer:

4/5

Step-by-step explanation:

one and one third times as much sugar as chocolate chips

=> S + 1/3(S) = C

one and two thirds cups of sugar is used

=> S + 2/3(S) = ?

now criss cross the two:

S + 1/3(S) = C

S + 2/3(S) = ?

C×(S+2/3(S)) = S + 1/3(S)....find C

C = (S + 1/3(S)) / (S + 2/3(S))

= (3S + S / 3) / (3S + 2S/ 3)

= 3S + S / 3S + 2S

= 4S / 5S

= 4/5.
