75 percent of 104 is the same as 80 percent of what number?

Answers

104*.75=78
78/8=9.75(divide by 8 because 80%/8=10%)
9.75*10=97.5
97.5*.8=78

75% of 104 is 78 which is also 80% of 97.5

Your answer is 97.5

Final answer:

Using an equation, we found that 75% of 104 is equal to 80% of 97.5. The number that made these percentages equal was found to be 97.5.

Explanation:

To find the unknown number, we can setup an equation using percentages and solve for the unknown. The problem states that 75% of 104 is the same as 80% of some number. So, we can write this as an equation: 0.75 * 104 = 0.80 * X. Solving this equation will give the value of X.

First, calculate the value of 75% of 104, which is 0.75 * 104 = 78. Now, replace this value into the equation: 78 = 0.80 * X. To solve for X, we divide 78 by 0.8, which gives us 97.5.

Therefore, 75 percent of 104 is the same as 80 percent of 97.5.

Answers

Answer:

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

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

$\mathbf{r} =\mathbf{ \frac{\text{RBC}}{\text{WBC}}}$

Insert the values and do the division.

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