How I at least figure this problem out is I take a pencil and start on the right side of the 0 and make a loop to the left for each number and count until I get to the first two numbers that are between 1-9 when reading from left to right.

Anyways with that new decimal number, you multiply the decimal by ten to what ever number you counted, which was 7.
