The place of 7 in second number can be identified by using multiplication of number system.

The the second number 7 is on the place of the ten thousands.

Given:

The first number has a 7 in its tenth place.

As per the given question first number has 7 in its tenths place so the number would be 10 time greater than its self. Now find the number,

In the hundreds place.

Step-by-step explanation:

1. You know that the first number has a 7 in its tenths place. This means that it is after the decimal point. You can write is as following:

x.7

Where x represents the other digits.

2. The second number has a 7 with a value that is 1,000 times greater than the value of the 7 in the first number, this means that you can know the place of the 7 in the second number if you multiply the first number by 1,000, or in other words, move the decimal point three places to the rigth. Therefore:

x.7*1000=7xx

3. As you can see, the 7 is in the hundred place in the second number.

answer: 72: 111
