7/9- negative1/4
To subtract fractions, you need to have a common denominator. The denominator in this case is 36:
7/9 - 1/4 = (7/9)(4/4) - (1/4)(9/9) = 28/36 - 9/36
Subtracting the numerators:
28/36 - 9/36 = 19/36
To subtract fractions, we need to have a common denominator. The common denominator of 9 and 4 is 36.
To rewrite the expression with the common denominator, we can multiply the numerator and denominator of the first fraction, 7/9, by 4, and the numerator and denominator of the second fraction, -1/4, by 9. This gives us:
(7/9) - (-1/4) = (28/36) - (-9/36)
Next, we can simplify the expression:
(28/36) - (-9/36) = (28/36) + (9/36) = (28 + 9) / 36
Therefore, the final answer is:
(7/9) - (-1/4) = 37/36
To subtract fractions, we need to have a common denominator. The common denominator is the least common multiple (LCM) of the denominators. In this case, the denominators are 9 and 4.
To find the LCM of 9 and 4, we can list the multiples of both numbers until we find a common multiple. The multiples of 9 are 9, 18, 27, 36, 45, 54, 63, and so on. The multiples of 4 are 4, 8, 12, 16, 20, 24, 28, and so on.
By examining the lists, we can see that the least common multiple of 9 and 4 is 36.
Now, we need to rewrite the fractions with the common denominator of 36:
7/9 = (7 * 4) / (9 * 4) = 28/36
-1/4 = (-1 * 9) / (4 * 9) = -9/36
Now, we can subtract the fractions:
28/36 - 9/36 = (28 - 9) / 36 = 19/36
Therefore, 7/9 - (-1/4) is equal to 19/36.
