A) 0.5(recurring) = 0.9

use the fact above to convert 0.05 to a fraction

b) using part (a) or otherwise, convert 0.25 to a fraction in its simplest form

with this question

It sounds like you're saying 0.555... = 0.9. This is not true.

. Meanwhile, , so 0.555... < 0.9.

I guess you're supposed to be converting 0.0555... into a fraction using the fact that 0.555... = 5/9 (because the above has nothing to do with 0.05). Well,

Then for part (b), I think you're supposed to rationalize 0.2555..., and not just 0.25. We have

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the answer to this question is 3/19
