How do you know that 15/30 is greater than 1/3 but less than 2/3?

We know this because we can simplify 15/30 to 1/2. 1/2 of 3 is 1.5
So: 1/3 is less than 1.5/3
and
2/3 is greater than 1.5/3!
Hope That Helps!

Idon’t understand this but 90

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
