Nick has four pieces of licorice that are 1 2/3 inches long each. what is the total length of licorice?

8 inches

Step-by-step explanation:

1 2/3 is the same as 6/3

6/3 times 4 pieces = 24/3

24/3 = 8

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
