We know the fraction “2 and 2/3” is equal to 8/3, since 3 goes into 8 twice, which is 6, and 8-6=2 so we add 2. It takes Nim 8 thirds of an hour to weave a basket.
We need to know how many Nim can make in 8 hours a day. Eight hours (in thirds) would be 24/3 (basic division).
8/3 = 1 basket
24/3 = x baskets
x = 24/3 / 8/3
x = 24/3 * 3/8
We can get rid of the threes, which leaves us 24/8, and 24/8=3
So, Nim weaves 3 baskets in 8 hours.
Multiply this by the number of days he weaves them (5 — Monday to Friday) and we get 8*5, which equals 40.
