3/4 hr=60 times 3/4=45mins
45/6=7.5 letters
that is pretty slow if you ask me

1/4 times what=5/6
times 4/1 both sides
what=20/6
what=10/3
about 3 and 1/3 of the 1/4 in the 5/6

20mins=1/3hr so
1/3 times what=3.4
times 3/1 both sides
what=10.2
there are 10.2 of them

1yd=36in
3/4 times 36=27in
27/3=9
9 of them

16oz=1lb
3/4 times 16=12oz
12/2=6
6 cookies
