Select the gcf of these numbers.
48 and 60

Using Euclid's algorithm, the first number you check is their difference:

60 - 48 = 12

Since 12 divides both numbers evenly, that is your GCF.

If the difference does not divide both numbers evenly, you can repeat the procedure with the difference and the remainder from dividing the smallest of the other numbers by the difference. For example, ...

GCF(60, 44) = GCF(44 mod 16, 16) = GCF(12, 16) = 4

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)
