269, label A
317, label B
298, label C
327, label D

which number line shows the letters A,B,C, and D written above the number line to show each number rounded to the nearest ten?

Answer:

Third option listed

Step-by-step explanation:

To find where to plot each letter, we have to round to the nearest ten--called the tens place.

321  [tens place underlined]

when rounding to a certain place value [like tens, hundreds, etc.], we round the digit by rounding the digit to the right of it.

If the digit to the right (in this case, the ones place ; 321)

is less than 5, we keep the digit in the tens place the same (and write a 0 in the ones place)

if the digit is greater than or equal to 5, we round the digit up (increase it by 1, and then write 0 in ones place)

so, here are the letters rounded:

A 269 = 270    [9 is greater than 5]

B 317 = 320   [7 is greater than 5]

C 298 = 300    [8 is greater than 5, and we carry the 1 from the tens place]

D 327 = 330   [7 is greater than 5]

Now, to find each value on the number line, we can look for that number [below each tick/mark]

So, the third option listed is correct

hope this helps!!
