Question

Medal
First, divide the numbers to find the exact answer, rounded to the nearest thousandth. Then use front-end estimation to determine whether the quotient you calculated is reasonable.
8.483 ÷ 2.3
calculated ?
estimated ?

Answer 1

anyone please help me

Answer 2

Well, first you divide 8.483 by 2.3. Use a calculator for precision.

Answer 3

The thousandth is 3 numbers to the right of the decimal place.

Answer 4

its 3.68826087

Answer 5

so for estimated its 36800

Answer 6

No. Front-end estimation is estimating the first number and leaving the rest zero.
Example
7,645 = 8,000
Got it?

Answer 7

ya 3.68800000

Answer 8

But remember for the calculated answer, only go to the nearest thousandth. So it would be 3.688.

Answer 9

No, estimate only the FIRST number, the 3.

Answer 10

Example
9.547 = 10.000
or
4.343 = 4.000
Got it?

Answer 11

@harz360 if you don't respond soon, I'm going to bed. It is late and I stay up helping people with their homework cause I am weird. haha

Answer 12

i just dont understand

Answer 13

Okay, do you get what front=end estimation is?

Answer 14

no

Answer 15

Front end estimation means you estimate only the first number. No matter how big or small the number.
Example
6,843
You will only estimate the first number, and in this case it is a 6. So you will evaluate the next number, 8. Since 8 is more than 4, the 6 will round up = 7. So your final answer will be 7,000. Get it?
So in your problem, 3.688. You will only estimate the first number, or the 3 in this case.
Since 6 is greater than zero, you can conclude that...

Answer 16

3.680

Answer 17

am i right

Answer 18

Only estimate the three, leave the other numbers, so all the numbers after 3, zeroes.

Answer 19

Okay, let's just take the first two numbers, 3.6
Estimate that.

Answer 20

3.6000

Answer 21

No, just estimate 3.6

Answer 22

I'm sorry, round 3.6 to the nearest one.

Answer 23

so its just 3.6?

Answer 24

No, just forget the other numbers. What

Answer 25

oh i see so the estimate is just 3.6

Answer 26

No, no. Estimate 3.6 to the nearest 1. Leave just one number.

Answer 27

so the nearest thousandths is 3 numbers

Answer 28

Yes, but you only need that for the calculated answer. For the estimated answer, you want to estimate it so that it is a one-number answer

Answer 29

so its just 3 right

Answer 30

and for calculated its 3.688 right

Answer 31

Well, look at the number after it. It is a 6. So it will be raised.

Answer 32

3.788

Answer 33

When you round a number, the number after it (in this case, a 6 (3.6)) determines if it will stay the same or go up a number. Since 6 is greater than four, the estimated answer is 4.000

Answer 34

Get it?

Answer 35

yes and calculated answer is 3.788

Answer 36

No, the calculated answer is 3.688. You round only the last number.

Answer 37

so its 3.689

Answer 38

or just stays as 3.688

Answer 39

No, it stays 3.688 because the original answer is 3.68826087, and you round to the nearest thousandth, which would be 3.688
