IF AXYZ is dilated by a scale factor of 5, which statement is true of the image AX'Y'Z'?

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

so, converting firstly the mixed fractions to improper fractions and then "adding".
