1/2 divided by 4 in fraction

1/8 = 0.125

Step-by-step explanation:

Here is 1/2 divided by 4 displayed mathematically in colors:

1/2

 ÷    

4

The numbers in 1/2 divided by 4 are labeled below:

1 = numerator

2 = denominator

4 = whole number

To make it a fraction form answer, you keep the numerator and multiply the denominator by the whole number to make a new denominator:

1/2 x 4

 =  

1/8

Thus, the answer to 1/2 divided by 4 in fraction form is:

1/8

To make the answer to 1/2 divided by 4 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

1/8 = 0.125

The answer is rounded to the nearest four decimal points if necessary.

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
