How many hours is nine minutes
Give reasons
One hour = 60 minutes, so 9 minutes = 9,60 = 3,20 hours

How many minutes is (nine fourths) °? How many seconds is it?
Solve!
One degree equals 60 minutes, one minute equals 60 seconds
So nine fourths of a degree is 80 / 3 minutes, 1600 seconds
1 / 3 plus 3.8 times 1 / 3 plus 4.2 times 1 / 3 is calculated by a simple method
1/3+3.8x1/3+4.2x1/3
=1/3x(1+3.8+4.2)
=1/3x9
=3
How many minutes is 450 seconds? How many degrees?
Equal to 450 △ 60 = 7.5 points
Equal to 7.5 △ 60 = 0.125 degrees
450÷60=70………… Thirty
450 seconds = 70 minutes 30 seconds = 1 degree 10 minutes 30 seconds
2 / 9 plus 3 / 9 plus 4 / 9 plus 2 / 9 times 5 / 9
2 / 9 + 3 and 4 / 9 + 2 / 9 * 5 and 5 / 9
=2 / 9 * (3 + 4 / 9 + 5 + 5 / 9)
=2/9*9
=2
