Q. Which inequality correctly orders the numbers −45,−221, and −0.1 ?Choose 1 answer:(A) −0.1>−221>−45(B) −221>−45>−0.1(C) −45>−221>−0.1(D) −0.1>−45>−221
Convert to Decimals: First, let's convert all the numbers to decimals to make it easier to compare them.−45 is already a fraction, which is equal to −1.25 when converted to a decimal.−2(21) is −2.5 when converted to a decimal because 2(21) is the same as 2+21, which is 2.5.−0.1 is already in decimal form.
Compare Decimals: Now, let's compare the decimals. We know that −0.1 is the smallest negative number because it is closest to zero. Next, we compare −1.25 and −2.5. Since −1.25 is closer to zero, it is greater than −2.5.
Order Negative Numbers: Therefore, the correct order from greatest to least (keeping in mind these are negative numbers, so "greatest" means closest to zero) is: -0.1 > -1.25 > -2.5
Match to Answer Choices: Now, let's match our ordered numbers to the original forms in the answer choices:−0.1 is the same in the answer choices.−1.25 corresponds to −45.−2.5 corresponds to −221.
Match to Inequality: The inequality that matches our ordered list is:-0.1 > -\frac{5}{4} > -2\frac{1}{2}This corresponds to answer choice (D).
