Hi!
In my opinion, the easiest way to solve a problem like this is to find the greatest common factor (GCF) of the numerator and denominator and then divide both numbers by the GCF.
So first we need to find the factors of 45 and 72 and find the factor that has the most value that the two numbers both have.
45: 1, 3, 5, 9, 15, and 45
72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
It looks like the GCF is 9. Now we have to divide 45 and 72 by 9.
45 ÷ 9 = 5
72 ÷ 9 = 8
So the correct answer should be:
Hope this helps :)

Step-by-step explanation:
A. when subtracting fractions with the same denominator, simply subtract the numerators and keep that number over the original denominator. Thus 11/12-7/12 becomes 4/12. But, this answer is not reduced because 4 is a factor of both the numerator and the denominator. Thus, divide 4 by 4 and 12 by 4 to get the new numerator and denominator. Your final fraction is 1/3.
b. In this expression, the fractions do not all have the same denominator, so you cannot subtract them yet. Your largest denominator is 8 but not all the other denominators are factors of 8. So to make a common denominator with all the fractions, you need to find a number that all the denominators are factors of. One example in this case is 24. Each of these fractions must then be expressed in terms of this common denominator. To do this, you need to find what can be multiplied by the original denominator to make 24. In other words, divide 24 by the original denominator and multiply that answer by the original numerator. In the case of 1/2, 24/2 is 12 and 12 x 1 is 12. Thus, the new fraction is 12/24. The second fraction is also done this way: 24/8=3 and 3x1 is 3 so the new fraction is 324. The third fraction should be handled the same way: 24/4 is 6 and 6x3 is 18 so the new fraction is 18/24. Finally, in 1/6, 24/6 is 4 and 4x1 is 4 so the new fraction is 4/24. Then, like the previous problem, when you perform 12/24 + 3/24 + 18/24-4/24= 29/24. Since 29 is larger than 24, this should be reduced. Do this by subtracting the denominator from the numerator and keep the remaining fraction. The final answer is 1 and 5/24.
Answer: y=x^8-x^7+x^6-x^5+x^4+x^3+x^2+3
Step-by-step explanation:
here is an example function that satisfies the requirement:
y=x^8-x^7+x^6-x^5+x^4+x^3+x^2+3
if you plug in x=0,
you get y= 3, which satisfies (0,3)
if you plug in x=1,
you get y = 1 - 1 + 1 - 1 + 1 + 1 + 1 + 3,
you get y=6, which satisfies (1,6)
