3:1
1 to 30
1:3
3:4:5
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
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.
1:3
1 to 30
If the ratio of the three sides are 1:√(3):2, it's a 30-60-90 triangle
3:4:5
30 is not a ratio. In a ratio, two numbers are always specified, for example, 30:1. If that's what you mean, you can simply multiply both numbers - in this case, 30 and 1 - by any real number (both by the same real number), to get an equivalent ratio.
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)

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).
1:square root 3
1:2:root3 (where 2 is the hypotenuse.)
A 30-60-90 right triangle is one in which the three angles of the triangle 30, 60 and 90 degrees. The length of the sides of such a triangle have the ratio 1:2:square root of 3. The 1 is opposite the 30 degree angle, the 2 is opposite the 60 degree angle and the square root of 3 is opposite the 90 degree angle.
