4/n = 4/5

a. n=5
b. n=5/16
c. n= 3 1/5
d. n= 50

The answer A) n=5

Step-by-step explanation:

Find the least common multiple.

The left denominator is "N"

The right denominator is "5"

That's how you get the answer N=5

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

it alot will look like this 4.4

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
