Answer 5

Answer 6

haha kinds sorry i just really genuinely suck at these, sorry

Answer 7

its okay

Answer 8

Yes, we know it isn't B or C.

B
7/8 is more than one-half and we have one-half, that means the fractions would equal over 1

C
5/6 is over one-half and so is 2/3, so therefore it would be over 1

Now let's see if A or D is our answer

Choice A
\(\rm \color{#20bd23}{\dfrac{1}{3}+\dfrac{2}{5}~=~\dfrac{5}{15}+\dfrac{6}{15}}\)

All you need to do is add the numerators (the top numbers of the fractions). If the sum of the numerator is 15+ then this is not your answer

Answer 9

okay ty!

Answer 10

d probably
