7: 7, 14, 21, 28, 35, 42, 49.... and so on.

Answer:
7/8 and 5/6 are not equivalent
Step-by-step explanation:
Fractions are equivalent when you put them into your calculator and it gives the same number.
7 ÷ 8 = 0.875
5 ÷ 6 = 0.8333...
Since 0.875 ≠ 0.8333, 7/8 and 5/6 are not equivalent.
If you test for the other pairs, they will have the same decimal.
1/9 = 2/18 = 0.111...
3/16 = 9/48 = 0.1875
6/15 = 4/10 = 0.4
