1 answer:
The least common denominator is the Least Common Multiple (LCM) of the divisors 3 and 4. Since these numbers have no common factors, their LCM is
... 3·4 = 12
The least common denominator of your fractions is 12.
... 1/3 = (1/3)·(4/4) = 4/12
... 3/4 = (3/4)·(3/3) = 9/12

Answer:
n = 6
Step-by-step explanation:
9n - 6 = 5n + 18
Subtract 5n from each side
9n-5n - 6 = 5n-5n + 18
4n -6 = 18
Add 6 to each side
4n -6+6 = 18+6
4n = 24
Divide each side by 4
4n/4 = 24/4
n = 6

1). 16 Y= 164. ( then divided)
Y= 164 : 16
Y= 41 : 4
Y = 10 +1/4
2) 8z = 64. (then divided)
z= 64 :8
z= 8
3. D = A•B•C. ( divided)
D : A•B = C
C= D:AB
c. c= d divided by ab
