Answer 2

Answer:

1. The numbers a, b, c and d are in proportional if the ratio of the first two quantities is equal to the ratio of the last two quantities, i.e., a : b : : c : d and is read as 'a is to b is as c is to d'. The symbol ' : : ' stands for 'is as'.

2. A proportion is a statement that shows two ratios are equivalent. A quick way to tell whether two ratios form a proportion is to use cross multiplication.
