Question

basic concept of ratio ?

Answer 1

Answer:

The ratio of two like quantities a and b is the fraction ab, which indicates how many times b is the quantity a. In other words, their ratio indicates their relative sizes.

If x and y are two quantities of the same kind and with the same units such that y ≠ 0; then the quotient xy is called the ratio between x and y.

Let the weights of two persons be 40 kg and 80 kg. Clearly, the weight of the second person is double the weight of the first person because 80 kg = 2 × 40 kg.

Therefore, WeightofthefirstpersonWeightofthesecondperson = 40kg80kg = 12.

We say, the ratio of the weight of the first person to the weight of the second person is 12 or 1 : 2.

Answer 2
