can some one explain to me how fractions work who ever explains it well gets brainliest, adding, subtracting, multiplying, divid

Adding: When adding fractions, you want to make sure that the denominator is the same for both fractions. If they are already the same, just add both the numerators to get the answer. For example,
$\frac{3 }{5} + \frac{1}{5} = \frac{4}{5}$
If the denominator is different in both fractions, you have to find the least common denominator, or LCD. The LCD is the smallest number that both denominators can multiply into. For example, say you need to find
$\frac{1}{6} + \frac{1}{3}$

Multiply both the numerator and the denominator of (1/3) by 2 to get (2/6). This way, the denominators are the same and you can find the answer.
$\frac{1}{6} + \frac{2}{6} = \frac{3}{6}$
In the case that one denominator does not go into the other, find the smallest number they both multiply into. For example,
$\frac{1}{3 } + \frac{1}{4}$
Here, the smallest number that both 4 and 3 multiply into is 12. Multiply both fractions by the correct amount to make both denominators 12. It would then become
$\frac{4}{12} + \frac{3}{12} = \frac{7}{12}$
Subtraction: follow the same rules as addition, except subtract the numerators instead of adding them.

Multiplication: multiply both numerators and both denominators.
$\frac{2}{3} \times \frac{4}{5} = \frac{8}{15}$
Division: Flip one of the fractions and multiply.
$\frac{2}{3} \div \frac{4}{5}$
Becomes
$\frac{2}{3} \times \frac{5}{4} = \frac{10}{12} = \frac{5}{6}$
Hope this explains it all. Let me know if you have any questions :)

Answer:

Step-by-step explanation:

There is missing information in the task: HD║FG !!!!!

∠HDE ≅ ∠FGE and ∠EHD ≅ ∠EFG

ΔEHG ~ ΔEFG (AAA theorem of similarity)

m∠F = 22°

m∠G = 89°

Arrange the slopes from flattest to steepest. -3/2, 0, 4/3, undefined

Dovator [93]

To arrange the slopes we need to take their absolute values.
1. Undefined slope means a vertical line, so it is going to be steepest.
2.|4/3| = 4/3
3.|-3/2| = 3/2
4. 0 means horizontal line.

From flattest to steepest: 0, -3/2, 4/3, undefined.

There are eight people competing in the track meet this weekend. They are competing for 1st, 2nd, and 3rd place ribbons. How man

malfutka [58]

Answer:

Option C

Step-by-step explanation:

Assuming P represents the number of outcomes, n the number of competitors and r the number of places to be awarded....

$P = n! / ( n - r )!\\P = 8! / ( 8 - 3 )!\\P = 8! / 5!\\\\Algebra, P = 336 \\Solution = Option C$

There are 336 different possible ways for the winners to be chosen.

Hope that helps!
