perform the indicated operation.
1/3-1/8
1/3-1/8=___ (Type a whole number or a simplified fraction.)
To solve the operation 1/3 - 1/8, we need to find a common denominator. The common denominator of 3 and 8 is 24.
Then, we can rewrite the equation as:
(8/24) - (3/24)
Subtracting the numerators gives us:
8/24 - 3/24 = 5/24
Therefore, 1/3 - 1/8 = 5/24.
To subtract fractions, we need to have a common denominator. In this case, the least common denominator (LCD) of 3 and 8 is 24.
To convert 1/3 to a fraction with a denominator of 24, we multiply both the numerator and denominator by 8:
1/3 = (1 * 8) / (3 * 8) = 8/24
Now we can subtract the fractions:
8/24 - 1/8 = (8 - 3) / 24 = 5/24
Therefore, 1/3 - 1/8 = 5/24.
To subtract fractions, you need a common denominator.
The denominators of the given fractions, 3 and 8, are not the same. To find the common denominator, you need to find the least common multiple (LCM) of 3 and 8.
The multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27...
The multiples of 8 are: 8, 16, 24, 32, 40, 48, 56...
From the above lists, we can see that the least common multiple (LCM) of 3 and 8 is 24.
Now that we have the common denominator of 24, we need to rewrite both fractions with this denominator:
1/3 = (1/3) * (8/8) = 8/24
1/8 = (1/8) * (3/3) = 3/24
Now, we can subtract the fractions:
8/24 - 3/24 = (8 - 3) / 24 = 5/24
So, the answer is 5/24.
