What is 0.5 divided by 12.5

lisabon 2012 [21]

Answer:

0.04 or 4%

Step-by-step explanation:

-A fraction consists of two numbers and a fraction bar: 0.5/12.5

- The number above the bar is the numerator: 0.5

The number below the bar is the denominator: 12.5

-Divide the numerator by the denominator to get fraction's value: Val = 0.5 ÷ 12.5

Calculate fraction's value.

Divide the numerator by the denominator to get fraction's value: 

0.5 ÷ 12.5 

= 0.04

<h3> Calculate the percent value:</h3>

Note:100/100 = 100 ÷ 100 = 100% = 1Multiply a number by the fraction 100/100,... and its value doesn't change.0.04 =

= 0.04 × 100/100 

= (0.04 × 100)/100 

= 4/100 

= 4%;

<h3>In other words:</h3>

1) Calculate fraction's value.

2) Multiply that number by 100.

3) Add the percent sign % to it.

Answer:

0.5÷12.5 = 4%

A circular rug has an area of 32.15 <img src="https://tex.z-dn.net/?f=ft%5E%7B2%7D" id="TexFormula1" title="ft^{2}" alt="ft^{2}"

Oxana [17]

Diameter is twice the radius. A=πr^2.

First, solve for r:

32.15=πr^2

*Divide both sides by π*

10.2337=r^2

*Take the square root of both sides*

3.199=r

Multiply the radius by 2:

3.199*2=6.398

D. 6.4 feet

Half of a number plus 12 is 46

asambeis [7]

Let the number = x
x/2 + 12 = 46
x/2 = 46 - 12
x/2 = 34
x = 34 * 2
x = 68

So, your final answer is 68

Hope this helps!
