Question

The following question has two parts. First, answer part A. Then, answer part B.

Answer 1

Answer:

Her estimate is reasonable.She can make 25 completed centerpieces

Step-by-step explanation:

Estimate 20 flowers per centerpiece.  430 flowers divided by 20 flowers per centerpiece.

430 /20 is approximately 21 centerpieces.  Her estimate is reasonable.

430/20  Divide the top and bottom by 10

43/2  is  21*2 = 42   with 1 left over    21  1/2

We know we underestimated when we rounded 17 to 20.  Se we are a little under with 21.5

Exact answer:

430÷17

17 goes into 43  2 times  (17*2 = 34  43-34 =  9 left over)

17 goes into 90 5 time  (17*5 = 85  90-85 = 5 left over)

She can make 25 completed center pieces
