Answer:
Mallory flew in total 10,000 miles, rounded :D
Step-by-step explanation:
<em>Since we're using rounding to place values, first we have to have the total amount of miles flown by Mallory, so we make the sum:</em>
3,720 + 5,985 = 9,705 miles
<em>then, we have to round thefirst digit to the right following this rule</em>
0-4 is rounded down
5-9 is rounded up
<em>now, since the number we want to round is the first digit on the left (9), and following the rules above, we change the "9" for a "10". the rest of the numbers are now transformed into zeros (0)</em>
9,705 >>> rounding it up >>> 10,000
Let me know if you have any questions XD
