It is the quantitative relation between two quantities which reflects the relative size of both the quantities. It is simply the means to compare the quantities.
Example 1: Suppose in a classroom there are 20 boys and 40 girls. Find the ratio of boys to girls.
Solution: Here, the ratio of number of boys to the number of girls will be 20/40.
By using fraction, we can write 20/40 = 1/2.
Thus, the numbers of boys are half the number of girls in the classroom.
In terms of ratio, it is written as 1:2 and read as “1 is to 2”

Let the numbers be in terms of x.
Now we have 3x 4x and 5x
Acc. to the question:
3x X 4x X 5x = 480
60x = 480
x = 480 ÷ 60
x^3 = 8
x = 2 ( cube root of 8 is 2)
Now. 3x will be 3 times 2 》 3 x 2 = 6
Similarly, 4x = 4 x 2 = 8
and 5x = 5 x 2 = 10
Hence, the numbers are 6, 8 and 10.

Let the numbers be 3x , 4x and 5x
Product of numbers=480
3x×4x×5x=480
60x³=480
x³=480/60
x³=8
x=2
3x=3×2=6
4x=4×2=8
5x=5×2=10
Hence numbers are 6 , 8 and 10
