​

Answer 1

The numbres that the product of two successive multiples of 10 is 120 are: 30 and 40.

As we know, a multiple is the result of multiplying a number by an integer. In this case, the multiples of 10 are:

10,20,30,40,50,60,70,80,90,100,...

Two successive multiples of 10 can be:

10 and 20

20 and 30

30 and 40

40 and 50

...

But the condition is: The product of two successive multiples is 1200. So 30 and 40 are the numbers because:

30 * 40 = 1200
