Answer:
C, 5/8
Explanation:
140 and 224 obviously have the number 2 as their divisor, so lets divide them by 2.
140 / 2 = 70
224 / 2 = 112
Again, they are both even so we divide by 2.
70 / 2 = 35
112 / 2 = 56
Looking closer, we realize they are both dividable by 7.
35 / 7 = 5
56 / 7 = 8
5/8 is the answer.
