well, an hour is 60 minutes so you do 60/3=20 so 3 fourths of an hour is 20.
27/20 or 2 and 7/20
3 fourths of 20 is 15
20
3/20
17/20
11/20
15/20 minus 6/20 which is 9/20 or 0.45
1 15/20 = 35/20
5 ÷ 3/4 = 20/3 or 62/3
If we convert into twenty-fourths we get 9 twenty-fourths + 20 twenty-fourths. So the answer is 29 twenty-fourths, which is just over 6 fifths.
It is 3/4 times 3/5 = 9/20
