Answer: 6/35
Step-by-step explanation:
Let's rewrite each given fraction with a common denominator of 5*7 = 35.
1/5 = (1/5)*(7/7) = 7/35
1/7 = (1/7)*(5/5) = 5/35
Then we can see that 6/35 is between 5/35 and 7/35, since 6 is between 5 and 7.
Put another way: 5/35 < 6/35 < 7/35 since 5 < 6 < 7
This then means 1/7 < 6/35 < 1/5
Therefore, Maria's claim is incorrect.
