If 23/8, 11/2, 9/6, and 15/7 are placed in order from least to greatest, which would be first?

Step-by-step explanation:

The given fractions are;

The least common denominator is .

We express all the fractions in equivalent form with the LCD as the denominator.

We now compare the equivalent forms and arrange from the least to the greatest.

This implies that,

Therefore the first would be .

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.
