Answer:
Explanation:
To make one bolt fixture, Harry needs 1 bolt, 1 washer, and 1 nut.
Bolts are sold in packs of 20, so Harry needs to buy at least 1 pack of bolts, which will give him 20 bolts.
Washers are sold in packs of 24, so to use all the bolts, Harry needs to buy a multiple of 20 packs of washers, which will give him a total of 20 x 24 = 480 washers. The smallest number of packs of washers he can buy is 20 packs.
Nuts are sold in packs of 25, so to use all the bolts and washers, Harry needs to buy a multiple of 20 x 24 packs of nuts, which will give him a total of 20 x 24 x 25 = 12,000 nuts. The smallest number of packs of nuts he can buy is 480 packs (since 480 packs of nuts will give him 480 x 25 = 12,000 nuts).
Therefore, the smallest number of packs of bolts, washers, and nuts Harry needs to buy to make bolt fixtures is:
1 pack of bolts
20 packs of washers
480 packs of nuts.
