1/4 - 1/7 as a fraction simplest form
To find the difference between two fractions, we need to have a common denominator. The common denominator for 1/4 and 1/7 is 28.
Therefore, the equivalent fractions are 7/28 and 4/28.
To calculate 1/4 - 1/7, we subtract the numerators: 7/28 - 4/28 = 3/28.
Therefore, 1/4 - 1/7 equals 3/28 in simplest form.
To subtract the fractions 1/4 and 1/7, we need to find a common denominator. In this case, the least common denominator (LCD) is 28 since it is the smallest number that both 4 and 7 divide into evenly.
Now, let's convert the fractions to have the same denominator:
1/4 = (1/4) * (7/7) = 7/28
1/7 = (1/7) * (4/4) = 4/28
Now we can subtract the fractions:
7/28 - 4/28 = (7 - 4) / 28 = 3/28
So, the difference between 1/4 and 1/7 is 3/28.
To find the difference between two fractions, we need to have a common denominator.
In this case, the denominators are 4 and 7. To find a common denominator, we need to determine the lowest common multiple (LCM) of 4 and 7.
The multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, ...
The multiples of 7 are: 7, 14, 21, 28, 35, 42, ...
From the lists, we can see that 28 is the smallest number that appears in both lists. Therefore, 28 is the LCM of 4 and 7, and this will be our common denominator.
Now let's convert our fractions to have a denominator of 28:
1/4 = (1 * 7) / (4 * 7) = 7/28
1/7 = (1 * 4) / (7 * 4) = 4/28
So now we have the two fractions as 7/28 - 4/28.
To subtract fractions, we keep the common denominator and subtract the numerators:
7/28 - 4/28 = (7 - 4) / 28 = 3/28
Therefore, the simplified form of 1/4 - 1/7 is 3/28.
