Could you explain how to do this, please???

Step-by-step explanation:

The value of b must be the same in both comparisons

a : b = 3 : 8 = (3 × 3) : (8 × 3) = 9 : 24

b : c = 6 : 11 = (6 × 4) : (11 × 4) = 24 : 44

The comparisons :

a : b : c = 9 : 24 : 44

The value of :

a + b + c = 9 + 24 + 44 = 77

So, the smallest possible value of a + b + c is 77

Hope it helpful and useful :)

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)
