one week, a construction worker bought 40 1/10 pounds of nails.
the next week he bought 2 1/2 times as many nails as the week before
how many pounds of nails did he but the second week?
16 1/25 Ib
99 1/4 Ib
80 1/20 Ib
100 1/4 Ib
The construction worker bought 40 1/10 pounds of nails the first week.
The second week, he bought 2 1/2 times as many nails as the first week, which equals:
40 1/10 x 2.5 = 100 1/4 pounds
Therefore, the construction worker bought 100 1/4 pounds of nails the second week.
So, the correct answer is 100 1/4 lb.
