I'm not sure you've written your question properly. As written I see:
(¾)/4 and 2/3
But (¾)/4 = ¾ ÷ 4 = ¾ × ¼ = 3/16
→ want lcd for 3/16 and 2/3
→ lcm(16, 3) = 48
If you actually mean lcd for 3/4 (or three quarters) and 2/3 then:
want lcd for 3/4 and 2/3
→ lcm(4, 3) = 12
With fractions, we call it the least common denominator. In this case, it's 12.
At least two fractions are needed to determine a least common denominator.
You need at least two fractions to determine a least common denominator.
The least common denominator would be 50
At least one other fraction is needed to determine a common denominator.
You need at least one more fraction in order to have a common denominator.
A common denominator, though not the least one, is 200.
Two or more fractions or mixed numbers are required to have a least common denominator.
At least two fractions are needed to determine a common denominator.
The least common denominator between fractions 1 over 32 and 8 over 64 is 64.
There is no exact least common denominator. Six does not go into 38
