Explain Bot To add or subtract fractions, you need to have a common denominator.
In the given problem, the fractions have different denominators: 1/4 and 3/8.
To find a common denominator, you need to find the least common multiple (LCM) of the two denominators, 4 and 8.
The multiples of 4 are: 4, 8, 12, 16, 20, 24, ...
The multiples of 8 are: 8, 16, 24, 32, 40, ...
From the lists, you can see that the least common multiple (LCM) of 4 and 8 is 8.
Now that we have a common denominator, we can rewrite the fractions with the new denominator:
1/4 = 2/8
3/8 = 3/8
Now that the fractions have the same denominator, you can add or subtract their numerators:
2/8 + 3/8 = 5/8
So, 1/4 + 3/8 equals 5/8.
