Question

WHAT IS LEAST COMMON DENOMINTOR (LCD)?

Answer 1

Umm say you have 1/3 + 1/4 .
You can't add fractions that don't have the same denominator.
Sooooo .. you find the lowest common denominator.
Multiply the 3 by 4 and the 4 by 3
And .. What you do to the denominator you must do to the numerator.
1/3 + 1/4
= 1x4/3x4 + 1x3/4x3
= 4/12 + 3/12
= 7/12
