How many different ways can you write a fraction that has a numerator of 2 as a sum of fractions? Explain.

zhenek [66]3 years ago

Answer:

Step-by-step explanation:

1/5 + 1/5 = 2/5

1/7 + 1/7 = 2/7

1/3 + 1/3 = 2/3

There are an infinite number of these fractions. They must be 1 and 1 in the numerator, and the denominator must be relatively prime  to 2. The examples I have picked are prime in the denominator, but the rule is not without many exceptions. For example

1/9 + 1/9 = 2/9

I don't think you can pick an even denominator because it will reduce when put with two.  Oh wait 2/18 + 2/18 = 4/18 = 2/9 But these could be reduced before adding. Still, it might count. It depends on who is marking the question.

What about an odd and even denominator?

1/9 + 1/18 = 3/18 = 1/6  There must be something that works, but I can't come up with an example.

The answer would be 30 since for 180 pounds and 60 feet you would need to divide 180 by 60 to get the unit rate for the pressure and then multiply by 10 which would get you 30. Correct me if I’m wrong. Hope it helps :)

If the racetrack publishes that the odds in favor of a horse winning a race are 5 to 9, what is probability that the horse will
crimeas [40]
I divided 5 by 9 and multiplied it by 100 to get the percentage for the probability the horse will win. I got 55.55%. I subtracted 55.55 from 100 and got 44.45% chance of not winning the race.

If n = 2 + 6m and p = 2/n, what is the value of p when m = -1/2?
artcher [175]

Answer:

p = - 2

Step-by-step explanation:

Given

n = 2 + 6m ← substitute m = - \frac{1}{2} into the expression

n = 2 + 6(- \frac{1}{2} ) = 2 - 3 = - 1

Thus

p = \frac{2}{n} = \frac{2}{-1} = - 2
