To write one and twenty three hundredths as a fraction, denote the decimal 0.23 as 23/100 and add it to the whole number 1, resulting in 123/100, which is the fraction form.
To write one and twenty three hundredths as a fraction, you start by recognizing that the decimal is read as "one point twenty three." This means we have one whole plus twenty three hundredths, which can be written as 1 + 0.23. To express 0.23 as a fraction, we place the number 23 over the denominator 100, because there are two digits after the decimal, indicating the hundredths place. Therefore, we have ⅓/100.
Combining the whole number with the fraction, we write: 1 + ⅓/100 = ⅓⅓/100. This fraction can be simplified by combining the whole number with the fraction part, resulting in 123/100, since 1 is equivalent to 100/100. To provide a So answer is: one and twenty three hundredths as a fraction is 123/100.
So, writing decimals as fractions involves understanding place value and writing the numerical part over the corresponding power of 10. The explanation included the conversion process from decimal to fraction and simplification steps to arrive at the answer.
