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 <em>tens place.</em>
<em />
3<u>2</u>1 [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<em>.</em>
<em />
If the digit to the right (in this case, the ones place ; 32<u>1</u>)<em> </em>
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]
<em />
So, the third option listed is correct
hope this helps!!
