1. Order the following sets of numbers from least to greatest: 15, radical symbol 18 , 2π
2. Order the following sets of numbers from least to greatest: 250^0, β525, (7^2-1)
3. Di and Leo both write the decimal 2.55555555.. As a fraction.
Diβs fraction: 2 55/100
Leoβs fraction: 2 55/99
Who is correct and why?
Leo is correct.
In decimal form, 2.55555555.. can be expressed as the repeating decimal 2.55. The pattern repeats indefinitely, so it can be represented as the fraction 2 55/99. Di's fraction, 2 55/100, is not equivalent to the decimal 2.55555555..
Order the following sets of numbers from least to greatest: 15, radical symbol 18 , 2π
To order these sets of numbers from least to greatest, we need to compare their values.
First, let's determine the approximate values of each number:
15 β 15
β18 β 4.2426
2π
β 6.2832
From least to greatest, the order is:
15, β18, 2π
Order the following sets of numbers from least to greatest: 250^0, β525, (7^2-1)
To order these sets of numbers from least to greatest, we need to compare their values.
First, let's calculate the values:
250^0 = 1
β525 β 22.9129
(7^2-1) = 48
From least to greatest, the order is:
1, β525, 48
