Answer 2

7.8 is the answer.

• In the given number, 78, the place value of 8 is 8. Let b be some other number where the place value of 8 is one-tenth of 8 in 78.

• Multiplying 8 by $\frac{1}{10}$ gives us 0.8

        Thus, in the new number, the digit 8 should appear as 0.8 for its value.

• The number 78, when multiplied by, gives 7.8. Here, if we represent the number as 78 = 7 + 0.8, we can see that 0.8 is one-tenth the value of 8 in 78
