Question

A pound of ground beef costs $5. what is the cost of 1/2 pound?

Answer 1

simple $2.50

Explanation:

1 pound is $5 so half of that is $2.50

Answer 2

$2.50

Explanation:

x/5 = 1/2

x is equal to 1 because it is half of the total and 1 is half of 2.

5 is equal to 2 because it is the whole amount and 2 is also the whole amount.

If you then solve for x by doing

5(1) = 5

5/2 = 2.5

You get 2.5 or $2.50.
