Answer:
28 bikes are blue
Step-by-step explanation:
Set up the ratio:
Blue : Black
4 : 5
Find the total # of bikes in the ratio:
4 + 5 = 9
Find the relationship between 63 and 9:
63/9 = 7
Multiply both sides of the ratio by 7:
4(7) = 28
5(7) = 35
28 : 35
Therefore, the number of blue bikes is 28.

1 hour 12 minutes or 1.2 hours
Step-by-step explanation:
You add fractions to get this.
1 room/3 hours + 1 room / 2 hours = 1 room / x
0.33333333+0.5 = 1 room / x
0.83333333 = 1 / x Multiply both sides by x
0.83333333x = 1 Divide by 0.8333333
x = 1/0.833333
x = 1.2 hours or
x = 1 hour and 12 minutes
