simplify mathematical operations such as addition of the fractions.
- The mistake is the LCD of 3 and 4 is 12 rather than 24
Reasons:
The given fractions are;
The Lowest Common Denominator, is given by the Least Common Multiple of the denominators, which is 3 × 4 = 12
Therefore;
The LCD = 12
The equivalent fractions are therefore;
Therefore, the mistake is using a LCD of 24 rather than 12, given that 12 is lower than 24 and therefore is the LCD of 3 and 4.
By having an LCD of 12, we have;
The equivalent fractions with the LCD will be;
