The right answer is Option D: \frac{27}{4}

Step-by-step explanation:

Given expression is

2(x+4)-(y.8)

x = \frac{1}{8}

y= \frac{3}{16}

Putting value of x and y in given expression;

2(\frac{1}{8}+4)-(\frac{3}{16}.8)

Taking LCM;

2(\frac{1+32}{8})-(\frac{3}{16}*8)

2(\frac{33}{8})-(\frac{3}{2})\\\frac{33}{4}-\frac{3}{2}\\

Taking LCM;

\frac{33-6}{4}\\\\\frac{27}{4}

The value of given expression is \frac{27}{4}

The right answer is Option D: \frac{27}{4}

Keywords: LCM, fraction

The average adult human has approximately 2.5 X 10' red blood cells and 7 X 10' white
Anit [1.1K]

Answer:

\large \boxed{r =\dfrac{\text{RBC}}{\text{WBC}};\,\text{400 times}}

Step-by-step explanation:

I think your missing numbers are

RBC = 2.5 × 10¹³ and  

WBC = 7    × 10¹⁰

This is a ratio question.

You are asked to find the ratio of RBCs to WBCs.

Let r = the ratio.

Then the equation for the ratio is

\mathbf{r} =\mathbf{ \dfrac{\text{RBC}}{\text{WBC}}}

Insert the values and do the division.

\begin{array}{rcl}r& =& \dfrac{\text{RBC}}{\text{WBC}}\\\\& =&\dfrac{2.5 \times 10^{13}}{7 \times 10^{10}}\\\\& =&\mathbf{400}\\\end{array}\\\text{The number of RBCs is $\large \boxed{\textbf{400 times}}$ as great as that of the WBCs.}
