Question

- Which list represents the numbers arranged in descending order? :A)1.55x10^1,√155,155%,1/5,-15/3.B)√155,155%,1/5,1.55x10^1,-15/3.C)155x10^1,√155,155%,1/5,-15/3.D)-15/3,1.55x10^1,√155,155%,1/5.

Answer 1

Arranging in descending order means arraging the numbers frim the largest to the smallest.

Given the following values according to the options

1.55x10^1, √155, 155%, 1/5, -15/3.

Let us rewrite all the values as whole numbers and decimals

1.55x10^1 = 15.5

√155 = 12.45

155% = 155/100 = 1.55

1/5, = 0.2

-15/3 = -5

The largest value is 15.5, followed by 12.5 then 1.55, 0.2 and then -5th

The negative vakue there is the lowest value i.e -15/3

The arrangement from largest to smallest are;

1.55x10^1, √155, 155%, 1/5, -15/3

Option A is corect
