Write the following number using decimal notation: seven and forty-three thousand fifty-two millionths. Converting Decimals to Fractions Note that each of the decimals you have encountered thus far in this activity end after a few digits. Decimals such as these are referred to as terminating decimals. When a terminating decimal is written as a fraction or mixed number, the denominator corresponds to the place value of the rightmost digit in the decimal. This leads to the…
