Answer:
Step-by-step explanation:
In the US, the most common eraser that is sold are the regular Pink Press erasers. These, as shown in the image below, are roughly 2.2 inches long. The most commonly used paper clip size is about 1.375 inches long. Assuming that these are the items that Dave is using to measure, then we can calculate the size of the calculator which is 2 erasers long...
2.2 + 2.2 = 4.4 inches long
The calculator is roughly 4.4 inches long, we can also divide this number by the length of the paper clip to find out how many paper clips make up the calculators length
4.4 / 1.375 = 3.2 paper clips
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
21++82= 103 is the answer.
The fraction
To find this we need to realize that .66 can be converted to a fraction. The last 6 is in the hundredths place, so if we convert .66 to a fraction we will get:
If we simplify this fraction as much as we can, we will get to
To check this we can divide
. So, 2 ÷ 3 = .66, which is correct, so our answer is correct.
I hope this helped! Have an amazing day :)
