3/8-1/2
To subtract fractions, you need to have a common denominator.
The common denominator for 8 and 2 is 8.
So, you need to rewrite both fractions with 8 as the denominator.
3/8 = 3/8
1/2 = 4/8 (since 1/2 is equivalent to 4/8 when the denominator is multiplied by 4)
Now, you can subtract the fractions:
3/8 - 4/8 = (3-4)/8 = -1/8
Therefore, the answer is -1/8.
To subtract fractions, you need to have a common denominator. In this case, the common denominator is 8.
First, we need to rewrite 1/2 as an equivalent fraction with a denominator of 8. To do this, we multiply the numerator and denominator of 1/2 by 4:
1/2 * 4/4 = 4/8
Now that both fractions have a common denominator of 8, we can subtract them:
3/8 - 4/8
Since the denominators are the same, we can subtract the numerators:
(3 - 4)/8
Which simplifies to:
-1/8
Therefore, 3/8 - 1/2 = -1/8.
