Answer 1

To solve this problem, there are a couple things we need to do.  First of all, we need to figure out how much more she's running every day.  On day 1, she ran 3/16 of a mile.  On day 2, she ran 3/8 of a mile.  On day 3, she ran 9/16 of a mile.

How much are we adding each time?  To find that out, we need all of our fractions to have the same denominator so we can compare.  Let's give 3/8 a denominator of 16.  8*2=16.  What you do on one side of the fraction bar, you MUST do to the other: 3*2=6.  So, 3/8 = 6/16.

Day 1: 3/16.  Day 2: 6/16.  Day 3: 9/16.  Now do you see the pattern?  Every day, she runs 3/16 of a mile more.  That's the answer to part 1: 3/16.

So, how long will it take her to get over 1 mile?  Let's continue.  Day 3: 9/16.  Day 4: 9+3=12, so that's 12/16.  Day 5: 15/16.  Day 6: 18/16!  Since the numerator is bigger than the denominator, guess what?  That's more than one mile!!  So on the 6th time she runs, she ran 18/16 miles.  Keep in mind that 18/16 = 9/8 = 1 1/8 miles.

Answers: 3/16; 6th; 1 1/8 (or 9/8)
