B. 10/3 < 10/8
C 10/15 < 10/16
D 10/15 >10/16

Answers

Answer:

D 10/15 > 10/16

Step-by-step explanation:

The least common multiple of 2 and 5 is 10.

2/3 = 10/15

5/8 = 10/16

10/15 > 10/16

Find the geometric mean of the numbers. If necessary, give the awnser in simplest form. 2/3 and 1/2.The geometric mean is ____

Answers

Answer:

Geometric mean = 1/√3 or 0.58

Step-by-step explanation:

We have to find the geometric mean of the 2/3 and 1/2.

To find the geometric mean of n terms we use the formula

Geometric mean = $\sqrt[n]{a_(1)* a_(2)* a_(3)....a_(n)}$

By putting the values in the formula

Geometric mean $=\sqrt{(2)/(3)* (1)/(2)}$

$\sqrt{(2)/(6)}=(1)/(√(3) )$

geometric mean = 0.58

Answer:

0.577

Step-by-step explanation:

We are given the following two numbers and we are to find their geometric mean:

$\frac {2} {3}$ and $\frac {1} {2}$

We know the formula for finding the geometric mean:

Geometric mean = $\sqrt[n]{a_1.a_2.a_3...a_n}$

So putting in the given values in the above formula to get:

Geometric mean= $\sqrt [2] {\frac {2} {3} .\frac {1} {2} }$ = $\sqrt {\frac {1} {3} }$

Geometric mean = 0.577
