n is less than or equal to negative one over thirty five

n is less than or equal to one over thirty five

n is greater than or equal to forty one over thirty five

Answer 1

Explanation:

You add 3/5 to -4/7 by finding the least common denominator (the bottom part of the fraction).

LCD is found by listing the multiples of the denominators and finding the common one.

5: 5, 10, 15, 20, 25, 30, 35

7: 7, 14, 21, 28, 35

For 3/5 you would multiply the numerator (the top part of the fraction) and denominator by 7, getting 21/35.

For -4/7, you would multiply the numerator and denominator by 5, getting -20/35.

21 + (-20) = 21 - 20 = 1

1/35

The final answer is that n is less than or equal to 1/35.
