Answer 19

Do you know how to add fractions?

Answer 20

i am really bad with fractions they scare me

Answer 21

:/

Answer 22

When dealing with adding or subtracting fractions... you are concerned with getting the denominators to be the same... so the numbers at the bottom must be identical. We do this by multiplying one or both of the fractions to get the same denominator.

Answer 23

1/2 + 1/4

What can we multiply the 1st fraction by to get a 4?

Answer 24

yes lcd right? d\so it would be 2/4x+1/4x=16

Answer 25

Least common multiple... and yes you are correct!

Answer 26

So add them up and what do you get?

Answer 27

3/8? or 3/4

Answer 28

Denominator does not change when adding... so 3/4

Answer 29

ok

Answer 30

3/4x = 16

To get rid of the denominator we multiply both sides by it... so it looks like:

Answer 31

\[4(\frac{ 3 }{ 4 })=16(4)\]

Answer 32

ok

Answer 33

So clean that up for me.
