Answer 1

Step-by-step explanation:

Let the multiples be 10x and 10x + 10

and it is given that their sum is 210 .

According to the question , required equation :-

10x + 10x + 10 = 210

20x + 10 = 210

20x = 210-10

20x = 200

x = 200/20

x = 10

The numbers are :-

10x = 10 × 10 = 100

10x + 10 = 10 × 10 + 10 = 110

Answer :-

the smallest number is 100
