Write the following number using decimal notation: seven and forty-three thousandfifty-two millionths.Converting Decimals to FractionsNote that each of the decimals you have encountered thus far in this activity end after a fewdigits. Decimals such as these are referred to as terminating decimals. When a terminatingdecimal is written as a fraction or mixed number, the denominator corresponds to the placevalue of the rightmost digit in the decimal. This leads to the following procedure to convert adecimal to an equivalent fraction or mixed number.ProcedureConverting a Terminating Decimal to a Fraction or Mixed Number1. Write the nonzero integer part of the number and drop the decimal point.2. Write the fractional part of the number as the numerator of a fraction. The denominatoris determined by the place value of the rightmost digit.3. Reduce the fraction if necessary.
