Solve

Answer 1

9/35

LCM of 7 and 5 = 35

Explanation:

`(2)/(5) -(1)/(7) \\\\(2*7)/(5*7) -(1*5)/(7*5) \\\\(14)/(35) - (5)/(35)\\\\\\(14-5)/(35) \\\\(9)/(35)`

Answer 2

• Option B is correct.

Explanation:

To subtract fractions, we must check if the denominators of both fractions are the same.

• 2/5 - 1/7
• => 2 x 7/5 x 7 - 1 x 5/7 x 5
• => 14/35 - 5/35

Now, let's subtract for the result.

• => 9/35

Hence, Option B is correct.
