9/3- 5/4
To subtract fractions, we need to find a common denominator.
The common denominator for 3 and 4 is 12.
Now we can rewrite the fractions with a denominator of 12:
9/3 = (9/3) * (4/4) = 36/12
5/4 = (5/4) * (3/3) = 15/12
Now we can subtract the fractions:
36/12 - 15/12 = (36 - 15)/12 = 21/12
The simplified fraction form of 9/3 - 5/4 is 21/12.
To solve the expression 9/3 - 5/4, you need to find a common denominator for the fractions and then subtract the numerators.
Step 1: Finding a common denominator
The denominators of the fractions are 3 and 4, which are not the same. To find a common denominator, you can multiply these two denominators together. In this case, the common denominator is 3 * 4 = 12.
Step 2: Adjusting the fractions
To convert the fractions with denominators 3 and 4 into fractions with a common denominator of 12, you need to multiply the numerator and denominator of each fraction by a suitable number.
For the first fraction, 9/3, you need to multiply the numerator and denominator by 4:
(9/3) * (4/4) = 36/12
For the second fraction, 5/4, you need to multiply the numerator and denominator by 3:
(5/4) * (3/3) = 15/12
Step 3: Subtracting the fractions
Now that you have both fractions with a common denominator of 12, you can subtract their numerators:
36/12 - 15/12 = (36 - 15)/12 = 21/12
Step 4: Simplify the fraction (optional)
If you want to simplify the fraction, you can find the greatest common divisor (GCD) of 21 and 12, which is 3. Divide both the numerator and denominator by the GCD:
(21/3)/(12/3) = 7/4
So, the result of the expression 9/3 - 5/4 is 7/4, or 1 3/4 in mixed number form.
To subtract fractions, we need to have a common denominator. In this case, the common denominator would be 12.
Now, let's convert the fractions to have a denominator of 12:
9/3 = (9 * 4) / (3 * 4) = 36/12
5/4 = (5 * 3) / (4 * 3) = 15/12
So, the expression becomes:
36/12 - 15/12
Next, we can subtract the numerators and keep the denominator the same:
(36 - 15) / 12 = 21/12
However, we can simplify this fraction by dividing the numerator and denominator by their greatest common divisor, which is 3:
21/12 = (21/3) / (12/3) = 7/4
Therefore, 9/3 - 5/4 = 7/4.
