Question

Place the following numbers in ascending order.

A) 0.255, 2.53 x 10^-1, 25.55%, 250, 1000
B) 0.255, 2.53 x 10^-1, 25.55%, 1000, 250
C) 2.53 x 10^-1, 0.255, 25.55%, 250, 1000
D) 2.53 x 10^-1, 0.255, 25.55%, 1000, 250

Answer 1

To determine the correct ascending order of the given numbers, convert all to decimal form, compare, and order them from smallest to largest. The correct ascending order is 2.53 x 10^-1, 0.255, 25.55%, 250, and 1000, making Option C the correct answer.

Step-by-step explanation:

The question involves placing the given numbers in ascending order. To compare the numbers, it's best to express them all in the same format. Here are the numbers converted to decimal form:

• 0.255 is already in decimal form.
• 2.53 x 10^-1 is the same as 0.253 in decimal form.
• 25.55% is equivalent to 0.2555 in decimal form.
• 250 is already in decimal form and is equivalent to 2.5 x 10^2 when expressed in scientific notation.
• 1000 is also in decimal form and is equivalent to 1 x 10^3 in scientific notation.

Now, we order them from smallest to largest: 2.53 x 10^-1 (0.253), 0.255, 25.55% (0.2555), 250, and 1000. Therefore, the correct ascending order is:

1. 2.53 x 10^-1
2. 0.255
3. 25.55%
4. 250
5. 1000

Option C is thus the correct answer.
