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

$\sqrt{2} \times \sqrt{2} = 2$

$\pi \times \pi = 9.86960....$

the 1st product (2) can be written as a fraction but the second one cannot be written as a fraction
