Question

I need to know how to answer this it hard

Answer 1

B) 0.18

To convert 2/11 into decimal form, divide 2 by 11 using a calculator or long division.

The result is 0.18181818... (the pattern of 18s repeats indefinitely).

Therefore, 2/11 as a decimal is approximately 0.1818 (rounded to four decimal places).

Answer 2

B.
`0.\overline{18}`

Explanation:

2/11 in decimal form is a set of repeating 18's:

0.181818181818...

This can be represented using bar notation, where digits under the bar repeat infinitely:

`0.\overline{18}`

Extra note:

A trick for fractions with 99 in the denominator is that, when the fraction is converted into a decimal, the numerator of the fraction is the repeating two digits.

In this problem, when we convert 2/11 to 99ths:

`(2)/(11) \cdot (9)/(9) = (18)/(99)`,

we can see that 18 is in the numerator, so that is the repeating part of the decimal
`0.\overline{18}`.
