Answer 20

@iGreen

Answer 21

Oh, I see. It's an addition problem.
You had "x" in it, so I thought it was the letter x as a variable.
Now that I see its an addition problem, you need to add two fractions.
The first thing you need to do to add fractions is to find a commion denominator.

Answer 22

Haha, hence why I asked if I had written it up correctly! :P

Answer 23

haha sorry people

Answer 24

\(\dfrac{9}{16} + -\dfrac{1}{4} \)

What is the least common multiple of 4 and 16?

Answer 25

32

Answer 26

32 is a common multiple, and we can use it, but notice that 16 is a multiple of 4, and any number is a multiple of itself, so the least common multiple of 4 and 16 is actually 16.

Answer 27

okay

Answer 28

9/16 + - 4/16

Answer 29

The fraction 9/16 already has the least common denominator of 16. We don;t need to work on it.
We need the common denominator of 16 in the fraction 1/4. We multiply the numerator and denominator by 4 to get the denominator of 16 that we need.

Answer 30

Oh, I see. You're ahead of me.
Correct.
Now we need to add the fractions.
To add fractions with the same denominator, we just add the numerators and write the same denominator.
What is 9 + (-4) = ?

Answer 34

Correct.
Here is the complete problem:
\(\dfrac{9}{16} + - \dfrac{1}{4} \)
