To solve this expression, you have to find a common denominator and then add the fractions.
Firstly, identify the common denominator for both fractions, which is 4.
Now, convert the first fraction, 9/4, to have a denominator of 4. You can accomplish this by multiplying the numerator and denominator by 1, which doesn't change the value of the fraction:
(9/4) * (1/1) = 9/4
The second fraction, 2/1, already has a denominator of 1.
Now that both fractions have a common denominator of 4, you can add them together.
9/4 + 2/1 = (9 + 2) / 4 = 11/4
Therefore, 9/4 + 2/1 equals 11/4.
can u explain how to do this, im a little stuck
