Question

A number is divided into two parts such that the difference between them is 18. The ratio of the two parts is 7 : 3.
Find the number and its two parts.

Answer 1

Answer:

Step-by-step explanation:

7x= 3x-18

10x=-18

X=- 1.8

Answer 2

Let the numbers be 7x and 3x

It is clear that 3x will be the smaller number.

It is also given that number is divided into two parts such that one part is 18 more than the other therefore,

7x-3x=18

4x=18

x=4.5

The two parts are

4.5*7=31.5

and

4.5*3=13.5
