What is Ratio and Proportion

1.  Ratio: The ratio of two quantities ‘a’ and ‘b’, in the same units, is the fraction (a/b) and we write it as a:b.

2. Proportion: The equality of two ratios is called proportion.

If a:b = c:d, we write, a:b::c:d and we say that ‘a’, ‘b’, ‘c’, ‘d’ are in proportion. Here ‘a’ and ‘d’ are called extremes, while ‘b’ and ‘c’ are called mean terms. Also, Product of means = Product of extremes.

Thus, a:b::c:d = (b × c) = (a × d)

3. Third Proportional: If a:b = b:c, then ‘c’ is called the third proportional to ‘a’ and ‘b’.

4. Fourth Proportional: If a:b = c:d, then ‘d’ is called the fourth proportional to ‘a’, ‘b’ and ‘c’.

5. Mean Proportional: Mean proportional between ‘a’ and ‘b’ is √ab.

6. If a > b and ‘x’ is a positive quantity, then (a/b) > {(a + x)/(b + x)} and (a/b) < {(a – x)/(b – x)}

7. If a < b and ‘x’ is a positive quantity, then (a/b) < {(a + x)/(b + x)} and (a/b) > {(a – x)/(b – x)}

8. If (a/b) = (c/d) = (e/f) = k, then:

i. {(a + c + e)/(b + d + f)} = k

ii. {(pa + qc + re)/(pb + qd + rf)} = k, where all ‘p’, ‘q’ and ‘r’ are either positive or negative real numbers.
