Question

A farmer has one square mile of land.
If he divides his land into square fields that are 1
-
2 mile long and 1
-
2
mile wide,how many fields will he have?

Answer 1

a field that is ½ by ½ has an area of ½*½ or namely ¼.

now, the farmer has 1 m² of land, if he divides it in ½ by ½ plots, how many of those plots will there be? namely how many times ¼ goes into 1?

$\bf 1\div \cfrac{1}{4}\implies 1\cdot \cfrac{4}{1}\implies 4$
