To solve this, set up the problem as a fraction: 60/90. Then reduce. The GCF of 60 and 90 is 30. Divide 30 into both 60 and 90 and you get a ratio of 2 to 3.

Ratio 180 : 60 = 3 : 1
The ratio of 50 minutes to 1 1/2 hours is 5:9. Once the units are the same they can be cancelled out and the numbers reduced by any common factor until their highest common factor is 1. 1 hours = 60 mins → 1½ hours = 1½ × 60 mins = 90 mins Therefore the ratio is: 50 mins : 1½ hours = 50 mins : 90 mins = 50 : 90 = 5 : 9
90% of 54 = 90% * 54 = 0.9 * 54 = 48.6
It is: 3 to 2
If the ratio of the three sides are 1:√(3):2, it's a 30-60-90 triangle

60 to 90
60 degrees. An angle and its complement always add up to 90 degrees. Because the ratio is 1:2, you know that there are three parts total (add the two sides of the ratio to get the total number of parts). Therefore, you can restate the ratio as 1/3 to 2/3. 2/3 of 90 is 60. So, the angle of the complement is 60 degrees.
Assuming that 30-60-90 refers to the angles (in degrees), the ratio of the longer leg to the hypotenuse would be 1:cosine(30) = 1:sqrt(3)/2 or 2:sqrt(3)
The ratio of 90 to 18 is written as 90/18
It is called a 30-60-90 triangle and it is a right triangle whose sides are always in the ratio:1:2:Square root (3).
