Sagot :
Answer:
Step-by-step 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.
