15
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
11/20
3/20
17/20
20
15/20 minus 6/20 which is 9/20 or 0.45
1 15/20 = 35/20
To get three-fourths of a number, you multiply the number by ( \frac{3}{4} ). For example, if the number is 20, you calculate ( 20 \times \frac{3}{4} ), which equals 15. This method can be applied to any number to find three-fourths of it.
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.
