What is the least common multiple of 2 and 4

The least common multiple (LCM) of 2 and 4 is 4.

Explain 1/2 + 1/4

To add fractions, we need to have a common denominator. In this case, we need to find the least common multiple (LCM) of the denominators, which in this case is 4.

Once we have a common denominator of 4, we can rewrite the fractions as:

1/2 = 2/4
1/4 = 1/4

Now, we can add the fractions:

2/4 + 1/4 = (2 + 1)/4 = 3/4

Therefore, 1/2 + 1/4 equals 3/4.
