How do yo turn a fraction into a percent?

1 answer:

8 0

You divide the top of the fraction by the bottom and then multiply it by 100.

Example : 1/4
-you do 1 divied by 4 = 0.25
-then you mutiply 0.25 by 100
-and you will get : 25%

-Hope this helps.

There are fours ways to solve polynomial equations..........

Polynomial Equation Degree Example

Linear Equations 1 -3x + 1 = 4x + 5

Quadratic Equations 2 x2 – 6x + 9 = 0

Cubic Equations 3 x3 – 2x2 + 3x = -5

Quartic Equations 4 x4 – 2x2 = -4

It's really not that hard.....

The denominator of a fraction is two more than the numerator. If both numerator and denominator are decreased by six, the simpli

Answer:

$\dfrac{40}{42}$

Step-by-step explanation:

Let the numerator of the fraction=x

Since the denominator of a fraction is two more than the numerator.

Denominator=x+2

The fraction is therefore:

$\dfrac{x}{x+2}$

If both numerator and denominator are decreased by six, the fraction becomes:

$\dfrac{x-6}{x+2-6}$

The simplified result is $\dfrac{17}{18}$

Therefore:

$\dfrac{x-6}{x+2-6}=\dfrac{17}{18}\\$Next, we solve for x\\Cross multiply\\18(x-6)=17(x+2-6)\\18(x-6)=17(x-4)\\Expand the bracket\\18x-108=17x-68\\Collect like terms\\18x-17x=-68+108\\x=40$

Substituting x=40 into the initial fraction

$\dfrac{x}{x+2}=\dfrac{40}{40+2}=\dfrac{40}{42}$

Therefore, the original fraction is $\dfrac{40}{42}$

Determine the value of each variable in the figure below. Keep answers in simplest radical form.

Tanzania [10]

Answer:

a = 21

b = 63

c = 42√3

d = 21√3

Step-by-step explanation:

The sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. The given side (42) is the longest side of the smallest triangle, and the shortest side of the largest triangle.

That means the other sides of the smallest triangle will be ...

a = 42/2 = 21

a+b = 2(42) = 84

b = (a+b) -a = 84 -21 = 63

d = 21√3 . . . . middle-length side of the smallest triangle

c = 42√3 . . . . middle-length side of the largest triangle

The values of the variables are ...

a = 21
b = 63
c = 42√3
d = 21√3

Answer:

35% or 0.35

Step-by-step explanation

If 20 grams is 100%, that means each gram is 5% of the whole. So 7 time 5 is 35.
