If 10 wholes are divided into pieces that are each / dfrac12 2 1 start fraction, 1, divided by, 2, end fraction of a whole, how many pieces are there?

There are 20 pieces there

Step-by-step explanation:

Here we have 10 wholes, with each of the piece measuring 1/2

To get the number of pieces there, what we have to do is to divide the whole by the measure of each of the piece.

Mathematically that would be 10 / (1/2) = 10/0.5 = 20 pieces
