What is 7/8 as a percent? it wants me to show work so plz tell me how i get the answer!

= 0.875

= 87.5 %

Explanation:

7 /8

= 0.875

In percentage

= 0.875 x 100

= 87.5 %

Hello!

= 87.5%

___________________________________________________________

Here are two simple ways to convert a fraction to a decimal.

Divide the numerator of the fraction by the denominator.

7 ÷ 8 = 0.875

Then, multiply the decimal by one hundred.

0.875 × 100 = 87.5%

Divide 100 by the denominator.

100 ÷ 8 = 12.5

Next, multiply both the numerator and the denominator by the quotient.

The numerator is your answer. Add a percentage sign. 87.5%.

step-by-step explanation:

equation

you are asked to write the equation

  expression = 0

using the given expression. when you do that, you have

  2x^2-2x-12 = 0

factoring

you can see that each of the coefficients is even, so a factor of 2 can be removed immediately.

  2(x^2 -x -6) = 0

if you multiply the binomials (x+a)(x+b), you get

  (x +a)(x +b) = x^2 +(a+b)x +ab

this tells you the coefficient of x is the sum of two factors of the constant term. here, that means -1 is the sum of two factors of -6. we want to know those factors so we can factor the trinomial.

  -6 = -1×6 = -2×3 = -3×2 = -6×1

the factor pair that sums to -1 is {-3, 2}, so our factorization is

  2(x -3)(x +2) = 0

solutions

the solutions to this equation are the values of x that make the product zero. a product is zero only when only of the factors of the product is zero. here, that means

  x - 3 = 0

  x = 3 . . . add 3 to both sides of the equation

or

  x +2 = 0

  x = -2 . . . add -2 to both sides of the equation

the solutions to the equation are x=3 or x=-2. both of these values of x satisfy the equation—they make it be true.
