Hank has finished 7/9 of his homework. billy has finished 2/3 of his homework. who is closer to finishing his homework?

Hank is.

If you convert 2/3 to the denominator 9, then you'll get 6/9. 7/9>6/9.

Hank is.

If you convert 2/3 to the denominator 9, then you'll get 6/9. 7/9>6/9.

Hank is closer to finishing his homework. Here is why To answer this question you have to make both of the fractions have a common denominator. Since 3 can go into 9 you can just change the second fraction. You would divide the denominater by 3 so you get 9 and whatever you do to the denominater you would have to do to the numerator. So you would get 6/9. Hank has 7/9 and Billy only has 6/9 so Hank is closer

Step-by-step explanation:

From the information given:

mean life span of a brand of automobile = 35,000

standard deviation of a brand of automobile = 2250 miles.

the z-score that corresponds to each life span are as follows.

the standard z- score formula is:

For x = 34000

z = −0.4444

For x = 37000

z = 0.8889

For x = 3000

z = -2.222

From the above z- score that corresponds to their life span; it is glaring  that the tire with the life span 30,000 miles has an unusually short life span.

For x = 30,500

z = -2

P(z) = P(-2)

Using excel function (=NORMDIST -2)

P(z) = 0.022750132

P(z) = 2.28th percentile

For x =  37250

z = 1

Using excel function (=NORMDIST 1)

P(z) = 0.841344746

P(z) = 84.14th percentile

For x = 35000

z = 0

Using excel function (=NORMDIST 0)

P(z) = 0.5

P(z) = 50th percentile
