Ms. beard bought 10 acres of land. she plans to divide the land into smaller lots that are each 1/20 of an acre. how many smaller lots will she have

For this case we have the following expression:
 N = (total acres of land) / (smaller lots of land)
 Substituting the values we have:
 N = 10 / (1/20)
 Rewriting we have:
 N = 10 * 20
 N = 200 lots
 
 She will have:
 N = 200 smaller lots
