no, a ratio is like, eg.
if you but one blueberry in your bowl, and two starwberrys, the ratio would be 1 to 2/ 1:2.
you could ask your math teacher. :P
New Answer : Two ratios are proportional in mathematics if they can both be reduced to the same value by division Proportion is an equality of ratios, and ratio is a relationship between two numbers which can be defined as the division of one number by the other. The ratio 4/2 and 16/8 are in proportion because they both can be reduced to 2 by division. They may be written as 4:2::16:8, which is read as '4 is to 2 as 16 is to 8'.
You need ratios to find out what scale to use.
Well, I know one career that uses proportions. Being a baker, for example scaling a recipe up and down depending on the number of guests you have.
what are two equivlent ratios for 2:11
The ratios are not equal.
That's a lot like asking "How do you do a bicycle ?"Probably the most important step ... the one that must always be done first, andthe one that you haven't completed yet ... is to be sure you know and understandexactly what it is that you need to 'do' with the ratios or proportions that are beingdiscussed.

You can use the z test for two proportions. The link below will do this test for you.
The law of multiple proportions states that if two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers. Two examples of the law of multiple proportions are carbon monoxide, CO, and carbon dioxide, CO2, and water, H2O, and hydrogen peroxide, H2O2.
Ratios are very important part of mathematics. They teach us how to deal with proportions.
Ratios or fractions can be used to present proportions.

Rates are ratios ... Speed is a rate of distance per unit of time... ratio of distance to time. Proportions are two equal ratios, whether they are rates or not.
Proportions show a relationship between two equal ratios. They maintain equality when both sides are multiplied or divided by the same number. In a proportion, the cross-products are always equal.
A proportion is a statement about the equality of two ratios.A percentage can be understood as a proportion in which one of the denominators is 100.

I'm sure they use ratios and proportions at many different points in the practice of their profession. One obvious application is in construction of exact scale models of aircraft and their components for wind-tunnel tests.
