Answer:

0,3% and 0,003\frac{something}{100}

Step-by-step explanation:

To make it as a percent, remeber that you need to transform this fraction to \frac{something}{100}

Therefore, we can divide 1000 by 10, to get the 100.

So we have:

\frac{3}{1000} / 10 = \frac{3 / 10}{1000 / 10} = \frac{0,3}{100}

Note: 3 / 10 is 0,3 (you move the comma to the left as much zeros)

and 1000 / 10 is 100 (you cut the zeros)

As we know have a fraction that is 100 on the denominator, we assume that \frac{0,3}{100} is 0,3%

Now, to get the fraction as decimal, just use the same hint I gave in the other part of the exercise (you move the comma to the left as much zeros).

Therefore, \frac{3}{1000} is 0,003

For this you are adding two fractions together. You always want to make sure they are both improper or normal fractions and that they have a common denominator. To find a common denominator, you look at the denominators and look for a number (The smaller the better) that both can be multiplied by some number to get to. In this case, the common denominator is 10. To make the denominators the same you multiply by one so the value doesn't change. This is done by multiplying the numerator and denominator by the same number that results in the denominator becoming the common denominator.
2 1/2 = 5/2 × 5/5 = 25/10
2/5 × 2/2 = 4/10

When adding, the denominator remains the same and the numerators are added!
25 + 4 = 29
So the answer is 29/10 or 2 9/10 when converted back into a mixed number.
Hope this helped!

Answer:

x = -6/5

Step-by-step explanation:

distribute -4 on the left side of the equation first, then distribute 2 on the right side of the equation to get:

16x - 4 - 4x = 2x - 14 - 2

combine 'like terms':

12x - 4 = 2x - 16

subtract '2x' from each side to get:

10x - 4 = -16

add 4 to each side to get:

10x = -12

x = -12/10 or x = -6/5
