Answer:
15/20 is greater than 8/20 and 3/4 is greater than 2/5.
Explanation:
15/20 is greater than 8/20 because 15 is a bigger number than 8 (over the name denominator of course.
However, the second one requires more work.
Basically you want to make their denominators the same.
I will mulitply 3/4 by 5.
that equals 15/20.
I will mulitply 2/5 by 4.
That equals 8/20.
Thus, 3/4 is greater than 2/5.
And 3/4 is equal to 15/20.
And 2/5 is equal to 8/20.
Hope this helped! :)
