3/3 because you have Two numbers that are greater than three out of three numbers which will give you 2/3 and then you have four which is an even number out of three numbers which will give you 1/3 you add them together which will give you 3/3 and which will equal one whole
4/10 and 4/100 are the same because all you had to do was multiply both the numerator and denominator by 10. It is still the same amount. Hope this helps!
