Question

What is the LCD (Least Common Denominator) of 4 1/6 5 4/7?

Answer 1

Rewriting it as improper fractions if necessary:
25/6, 39/7

For the denominators (6, 7) the least common multiple (LCM) is 42.

Therefore, the least common denominator (LCD) is 42.

Rewriting the original as equivalent fractions with the LCD:
175/42, 234/42.

Here are the steps to follow:

Find the Least Common Multiple of the denominators (which is called the Least Common Denominator).

Change each fraction (using equivalent fractions) to make their denominators the same as the least common denominator

Then add (or subtract) the fractions, as we wish!
