While training for a marathon, Todd runs
12.5 miles on Monday, 15.6 miles on
Tuesday, 19.25 miles on Wednesday,
20.45 miles on Thursday, and 13 miles
on Friday. How many miles did he run
Monday through Friday?
You would add Monday through Fridays miles up, using basic addition with rounding. So 12.5 plus 15.6 equals 28.1 miles. Then you'd add 28.1 miles to 19.25 miles. And you'd add the number you add to the next number of miles.
