Answer:

6 3/8

Step-by-step explanation:

Convert the fractions so that the denominators match.

$3\frac{3}{4} =3\frac{6}{8}$ , then $3\frac{6}{8}=\frac{30}{8}$

$1\frac{1}{8}=\frac{9}{8}$

$2\frac{1}{2}=\frac{3}{2}$ , then $\frac{3}{2}=\frac{12}{8}$

Add up the fractions.

$\frac{30}{8}+\frac{9}{8}+\frac{12}{8} =\frac{51}{8} =6\frac{3}{8}$

Answer:

Conjecture : 2xy / ( x + y ) ≤ √xy

Step-by-step explanation:

Harmonic mean of x and y = 2xy/( x + y )

<u>Formulate a conjecture about their relative sizes </u>

we will achieve this by computing harmonic and geometric means

Geometric mean = √xy

harmonic mean = 2xy/( x + y )

Conjecture : 2xy / ( x + y ) ≤ √xy

attached below is the proof
