# How Many Stacks of 100 Pennies Can You Make Out of 10,000,000 Pennies?

**Ten million pennies divided into 100-penny rolls makes 100,000 stacks of pennies, based on problem-solving strategies described by the Monterey Institute for Technology and Education.** To obtain the answer, move the decimal point in 10 million two places to the left, since there are two zeros in the number 100.

Division and multiplication are inverse operations. Given that the product of a problem in which a number is multiplied by a power of 10 is obtained by relocating the decimal point to the right in accordance with the number of zeros in the power of 10, determining the placement of the decimal point when dividing any number by a multiple of 10 is achieved by doing the exact opposite.
