Danielle knows that a dollar bill is half a foot long. how could she use the dollar to measure a mat for her desk that should be 1 2/3 ft. by 5/4 ft?

(btw I'm in middle school not highschool)

For a lenght of a desk which needs to be 1 2/3ft long, Danielle can use 1 hole dollar bill and she will need 2/3ft more. 1/2ft*x=2/3ft, x=4/3.

So for lenght she will need 1 hole dollar bill and 4/3 of a dollar bill more.

For width of table she need 5/4ft. 1/2ft*x=5/4ft, x=5/2.

So for width of table she will use 5/2 of a dollar bill.
