Luci cuts a board that is 3/4 yard long into pieces that are
3/8. The pieces she cut can be solve by dividing the board by length of the new
board. The length of the ¾ yards long divided by the desired length of 3/8
yards which is equal to 2 pieces.
He graded 60/75 papers.
If you divide these numbers instead of trying to simplify it equals the decimal 0.8.
If you move the decimal point two places to the right it's 80%.
