Help me please! It's confusing.

C. 5/8 (62.5%), 65%, 2/3 (about 66.7%), 0.7 (70%)

Step-by-step explanation:

What we need to do here first is convert each of the values into percentages. 65% is already a percentage so don't worry about that.

(5*100)/8

500/8

125/2

62 1/2% or 62.5%

(2*100)/3

200/3

66 2/3% or about 66.7%

0.7 * 100

7 * 10

70%

Now, just sort these percentages by value. 70% is the greatest of these, so that's on the right. A and B, have 2/3 as the greatest (which is not right), so they're out. 5/8 (62.5%) is the smallest. Both C and D have this, so they're still possible. 65% however, is less than 2/3. D has this other way, so it is wrong, leaving C as our answer.
