Q. −1.2−2920= -1.2-\frac{29}{20}= \newlineEnter the answer as an exact decimal or simplified fraction.
  1. Convert to fraction: Convert the decimal to a fraction. \newline−1.2-1.2 can be written as −65-\frac{6}{5} because 1.21.2 is the same as 65\frac{6}{5} and we are considering the negative sign.
  2. Common denominator: Write the subtraction in terms of a common denominator.\newlineTo subtract −65-\frac{6}{5} and −2920-\frac{29}{20}, we need a common denominator. The least common denominator for 55 and 2020 is 2020.
  3. Convert to common denominator: Convert −65-\frac{6}{5} to a fraction with a denominator of 2020. −65-\frac{6}{5} is equivalent to −2420-\frac{24}{20} because 6×4=246 \times 4 = 24 and 5×4=205 \times 4 = 20.
  4. Perform subtraction: Perform the subtraction using the common denominator.\newlineNow we have −2420−2920-\frac{24}{20} - \frac{29}{20}. Subtracting the numerators gives us −24−29=−53-24 - 29 = -53.
  5. Write as fraction: Write the result as a fraction.\newlineThe result of the subtraction is −5320.-\frac{53}{20}.
  6. Convert to decimal: Convert the fraction to a decimal if necessary.\newlineSince the question prompt does not specify the format of the answer, we can leave it as a fraction. However, if we were to convert it to a decimal, −5320-\frac{53}{20} is equal to −2.65-2.65.
