Question

Select the set of numbers that are arranged from greatest to least.

OA) 2.4 x 10; 2.7 x 105; 3.1 x 105
OB) 3.1 x 10; 2.4 x 10;
2.7 x 105
OC) 2.7 x 105;
2.4 x 10¹;
3.1 x 10¹
OD) 3.1 x 10³; 2.7 x 105;
2.4 x 10

Answer 1

The set of numbers arranged from greatest to least is:

OC) 2.7 x 105; 3.1 x 10¹; 2.4 x 10¹0

To see why, let's convert each number to scientific notation, which makes it easier to compare them:

OA) 2.4 x 10 = 24

2.7 x 105 = 270,000

3.1 x 105 = 310,000

OB) 3.1 x 10 = 31

2.4 x 10 = 24

2.7 x 105 = 270,000

OC) 2.7 x 105 = 270,000

2.4 x 10¹ = 24

3.1 x 10¹ = 31

OD) 3.1 x 103 = 3,100

2.7 x 105 = 270,000

2.4 x 10 = 24

As we can see, the set of numbers in option OC is arranged from greatest to least, with 2.7 x 105 being the largest number, followed by 3.1 x 10¹, and then 2.4 x 10¹0 as the smallest number
