NES Elementary Education (102/103) Practice Test

When converting a terminating decimal to a fraction, the goal is to remove the decimal point by using a power of ten as the denominator. If there are two digits after the decimal, you multiply by 100 to shift the decimal two places to the right, write the resulting integer over 100, and then simplify. For example, 0.52 becomes 52/100, which simplifies to 13/25. This approach generalizes: one digit after the decimal means multiply by 10 and place over 10; three digits means multiply by 1000 and place over 1000, and so on. The option described matches the two-decimal case exactly. Subtracting the decimal from 1 isn’t a method to convert to a fraction, and doubling the decimal or using a single-step multiply-by-10-and-over-10 won’t reliably remove all decimal places for decimals with more than one digit after the point.
