STEP 1

Assumptions1. The record rainfall amount is twenty-eight and ninety-one hundredths inches.

STEP 2

We need to convert the verbal description of the number into decimal notation.The number "twenty-eight and ninety-one hundredths" can be broken down into two parts the whole number part "twenty-eight" and the fractional part "ninety-one hundredths".

STEP 3

First, let's write down the whole number part "twenty-eight" in decimal notation.
$$Whole\, number\, part =28$$

STEP 4

Next, let's convert the fractional part "ninety-one hundredths" into decimal notation."Ninety-one hundredths" means91 out of100, which can be written as a fraction as91/100.

STEP 5

We can write this fraction as a decimal by dividing the numerator by the denominator.
$$Fractional\, part = \frac{91}{100} =0.91$$

STEP 6

Finally, we combine the whole number part and the fractional part to write the number in decimal notation.We do this by adding the whole number part and the fractional part.
$$Decimal\, notation = Whole\, number\, part + Fractional\, part$$

STEP 7

Plug in the values for the whole number part and the fractional part to get the decimal notation.
$$Decimal\, notation =28 +0.91$$

Calculate the decimal notation.
$$Decimal\, notation =28 +0.91 =28.91$$The record rainfall amount for a24-hour period in a particular state is28.91 inches.
