Jacob’s recipe calls for 4 7/8 cups of raisins. He has 6/11 of the amount that he needs. About how many cups of raisins does Jacob have? Estimate by first rounding each number to the nearest 1/2.

OpenStudy (jhannybean):

Well, rounding to the nearest 1/2, or \(0.5\) of a decimal place, \(4 +\frac{7}{8} \approx 4.875\) so rounding up to the nearest 1/2 would be \(\approx 5\) then you have \(\dfrac{6}{11} \approx 0.54545... =0.5\) , the nearest 1/2.

OpenStudy (jhannybean):

Multiplying these together, you get the total approximation, which is\[5 \cdot 0.5 = \dfrac{5}{2}\]Change that to a mixed number, and you will have your answer :)

OpenStudy (anonymous):

sooooo C ????

OpenStudy (jhannybean):

2 goes into 5 two times, leaving a remaining 1/2.

OpenStudy (jhannybean):

There you go :) yes, C.
