Simplify the ratio. 45 minutes to 1 hour

1 hour can be simplified to 60 minutes because there are 60 minutes in one hour thus, the ratio becomes 45:60 if we want to simplify that even more, we have to divide both numbers by 5 45/5 = 9 60/5 = 12 therefore, the ratio becomes 9:12

H=hours
M=minutes
You convert 1 hour into 60 minutes
So your ratio would be 60:45
Then you find the common denominator, which the highest is 15
Divide by both
45÷15=3
60÷15=4
Therefore, your ratio would be 3:4

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
