Step-by-step explanation:
15/4 + (−4/13) can be rewritten as 15/4-4/13.
15/4-4/13
15 x13
4 x13
195/52
4 x4
13 x4
16/52
195/52-16/52=179/52 or 3 23/52
hope it helps!
If it is numbered one through ten you would put it on the 9 point
5^5 mod 7 = 3
5^4 mod 7 = 2
5^3 mod 7 = 6
3 -2 +6 mod 7 = 0
Therefore, 5^5 -5^4 +5^3 mod 7 = 0 and that sum is divisible by 7.
It's b because you have to round up
