Apainter spends three hours working on a painting. a sculptor spends 2 2/3 as long working on a sculpture. how long does the sculptor work?

Step-by-step explanation:

8 because 2 and 2/3 times 3 equals 8/3 times 3 and the threes cancel out and there is a 8 left.

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.
