He can because you can add it mentally. You can just have 23 in your head and count by adding 10 "4" times.
Hope this helped☺☺
Step-by-step explanation:
Since 1 mi. equals 5,280 feet, you divide 5,280 by 2 to get half of a mile.
5,280 / 2 = 2,640 is half of a mile
Then add to get the answer:
5,280 + 2,640 = 7,920
Therefore, your answer is 7,920, 7,920 is 1.5 miles.
It would be: 3/7-1/14 = 6-1 / 14 = 5/14
So, 5/14 is your answer..........
