First we have to get the LCM of 8 and 6, which is 24. so the fractions with be Maria 9/24 and Nina 12/24. therefore Nina are more
it's either a or b, not sure but I think it's b
1/4 3/5 3/4 7/5 7/3 is the correct order well at least i think it is but i hope it helps

b² = 625 - 49
b = √576
b = 24
In short, Your Answer would be Option B
Hope this helps!
