Did someone saw this and if you can explain to me how do you add and subtract and multiply and divide negative fractions are really don't understand this and saw that question for me you somebody

When you are adding or subtracting a negative fraction, you usually want to consider the numerator as negative. The method is just the same, except now you may need to add negative or positive numerators. To add the fractions with unlike denominators, rename the fractions with a common denominator. So you could find the lowest common multiple and multiply the numerator and denomenator by it and then you can carry on with the rest of the equation. If this doesn’t make sense and you need these information for an equation I suggest you take a picture of it and upload it so someone can help you with it specifically

Answer:

$4034.40

step-by-step explanation:

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
