A ratio is a relationship between two numbers indicating how many times the first number contains the second.
For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six (that is, $$\displaystyle{8}\div{6}$$, which is equivalent to the ratio $$\displaystyle{4}\div{3}$$).
Rate means the change in one variable with respect to change in other variable. For example speed is rate of change of distance with change in time.
A proportion is a statement that explains that ratios are equal, e.g. $$\displaystyle{1}\div{2}={3}\div{6}$$
Percentage is a measure of a portion in relation to a whole, often expressed in relation to how many of something there are per 100. When a group has half girls and half boys, this is an example of a situation where the percentage of boys in the group is equal to 50 percent.
A ratio compares two quantities of the same unit, e.g. if the ratio of my supply of apples to your supply of apples is $$\displaystyle{1}\div{2}$$, it means that for every 1 apple | have, you have 2. Ratios can also be expressed as fractions, e.g. $$\displaystyle{1}\div{2}$$ is $$\displaystyle{\frac{{{1}}}{{{2}}}}$$.
A rate compares two quantities of different units, e.g. mph or km/h. $$\displaystyle{m}{i}{d}{f}{m}{i}{d}$$ travel at a speed of 65 mph, it means for every 1 hour, | have traveled 65 miles and for every 65 miles | travel, | have spent 1 hour.
