How do you write 80% as a fraction, mixed number, or whole number in simplest form?

2 answers:

For the fraction you start off by putting 80 over 100 and start simplifying which gives you 4/5 as for a mixed number or a whole number it isn't possible since it isn't a total whole. In order for you to have a mixed number you need something over a whole or something over a 100%

A percent can be viewed as a fraction over 100, so in this case, we form the fraction 80/100.

However, this is not in simplest form. The largest number that goes into both of these (greatest common factor) is 20, so we should divide the numerator and denominator by 20.

When we do this, we can see that the simplest fraction to represent 80% is 4/5.

Make a system of equations and solve for each variable.

3m+8v=53
5m+2v=26

m= movie cost
v= game cost

multiply the bottom equation by 4(combination method)

3m+8v=53
20m+8v=104. Subtract

-17m = -51
m= 3

Plug back into one of the equations

5(3)+2v=26
15+2v=26
2v=11
v=5.5

m=$3
v=$5.5

The options Patel has to solve the quadratic equation 8x² + 16x + 3 = 0 is x = –1 Plus or minus StartRoot StartFraction 5 Over 8 EndFraction EndRoot.

<h3>Quadratic equation</h3>

8x² + 16x + 3 = 0

8x² + 16x = -3

8(x² + 2x) = -3

Using completing the square

8(x² + 2x + 1) = -3 + 8

factorization

8(x² + 1) = 5

(x² + 1) = 5/8

Taking the square root of both sides

(x + 1) = ± √5/8

x = -1 ± √5/8

Therefore,

x = –1 Plus or minus StartRoot StartFraction 5 Over 8 EndFraction EndRoot
