a ratio is a comparison between 2 or more things. To work ratio out, it will be easier if you separate it into parts. if you was to work out the ratio of money, you would add the ratio together. whatever the number is you convert into money. you would then times it by the first number of the ratio which is the answer of the first of the first part, then you add it to the second number, and then that is the answer to the ratio problem.
This is an example: if you had to work out £100 and the ratio was 8:2 this is how you would do it.
first part you add the 8 and the 2 together which is 10, convert that into money it is £10
second part you times the 8 and the £10 together which is £80
third part you times the 2 and the £10 together which is £20
then you put it in ratio which is £80:£20

Is The Ratio 35 To 10 Proportional To The Ratio 7 To 5 Explain?
No, it is not. 35 to 10 is a unit rate of 3.5 to 1 whereas 7 to 5 is a unit rate of less than 2 to 1.
How do you explain that 8 over 10 and 12 over 15 is equivalent to 4 over 5?
How you explain depends on your knowledge and that of the person tat you are trying to explain to. Start with the ratio of the integers 4 and 5 which is 4 over 5 or 4/5. If you separately multiply the numerator (4) and the denominator (5) by the number 2 you get 4*2 = 8 and 5*2 = 10 The ratio of these two numbers is 8/10 but because of the way you obtained these numbers, the ratio has the same value. That is, also the same as 4/5. Multiply both part of the original ratio by 3 to get 12/15. You can multiply the two numbers by any non-zero number to get an equivalent ratio although if you multiply by a fractional number, the results may be a bit hard to understand. For example, multiplying by 1/16 gives the ratio of 1/4 over 5/16. Not so easy to see the equivalence to 4/5 unless you know that dividing by a fraction is the same as multiplying by its reciprocal.
Explain why the tangent of 45 equals 1?
Tangent is determined by the ratio of the side opposite the angle over the one adjacent to it. In a 45-45-90 triangle, the ratio of these sides is 1. This is because the side opposite one of the 45 degree angles is adjacent to the other, and vise versa.

What is the ratio of the circumferences of two wheels if the ratio of their radii is 2 to 3?
The ratio of all lengths is the same. The ratio of the circumferences = ratio of the radii = 2:3
