How do u turn a fraction into a percent

2 answers:

5 0

Hello there,
To turn a fraction to a percent, you must multiply 100 to the fraction, since a percent is out of a hundred. For example 1/4 can be changed by doing 1/4*100. Multiply 100 to the numerator(top) and divide that answer to the denominator(bottom). 1*100=100÷4= 25%. Hope this helps!!

You multiply both the numerator and the denominator by the number that you need to multiply the denominator by to equal 100. Then your numerator is the percent.

Answer:

x = 40

Step-by-step explanation:

The ADF is 90 degrees so the CAF will also be 90

So you do

( x + 15 ) + 90 + 35 = 180

x + 15 + 90 + 35 - 90 = 180 -90

x + 15 + 35 = 90

x + 15 + 35 - 35 = 90 - 35

x + 15 = 55

x + 15 - 15 = 55 - 15

x = 40

The following equation is being multiplied by the LCD. Complete the multiplication to eliminate the denominators

frosja888 [35]

Answer:

$(x+2)(x-2) -1(3x)=(x-3)(x-2)$

Step-by-step explanation:

x+2/3x - 1/x-2 = x-3/3x

$\frac{x+2}{3x}-\frac{1}{x-2}=\frac{x-3}{3x}$

LCD is (3x)(x-2). so we multiply the whole equation by LCD

$(3x)(x-2)(\frac{x+2}{3x}-\frac{1}{x-2}=\frac{x-3}{3x})$

We multiply each term by LCD

$(3x)(x-2)(\frac{x+2}{3x})-(3x)(x-2)(\frac{1}{x-2})=(3x)(x-2)(\frac{x-3}{3x})$

$(x+2)(x-2) -1(3x)=(x-3)(x-2)$

Please Help ASAP! I suck at geometry :(

We know that for every 5 red bricks there were 2 gray bricks.

The total amount of red bricks and grey bricks in this sample is 7.

5 red bricks + 2 grey bricks = 7 bricks

Now, we divide 175 "total number of bricks used" by 7 "5 red bricks + 2 grey bricks = 7 bricks" and we will get a quotient of 25.

Now we know that 25 bricks is $\frac{1}{7}$ of the wall. The gray bricks are $\frac{2}{7}$ so we can multiply 25 by 2 and we will get a product of 50. If 1/7 = 25 grey bricks so 2/7 would be the grey bricks.

175 - 50 = number of red bricks.

Therefore, there were 125 red bricks.
