20 points me ! 2. when you are identifying the coordinate of a fraction or a mixed number on a number line, how do you determine the denominator?

By finding the LCM ( Least Common Multiple)

Step-by-step explanation:

Add by the multiples of both numbers until you end up with the same number for both.

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
