Answer 2

Calculation: 4/9 + 5/6 - 3/4

To calculate the expression 4/9 + 5/6 - 3/4, we need to find a common denominator for the fractions and then perform the addition and subtraction.

Let's find the common denominator first. The denominators of the fractions are 9, 6, and 4. The least common multiple (LCM) of these numbers is 36.

Now, we can rewrite the fractions with the common denominator of 36:

4/9 = (4 * 4) / (9 * 4) = 16/36 5/6 = (5 * 6) / (6 * 6) = 30/36 3/4 = (3 * 9) / (4 * 9) = 27/36

Now, we can perform the addition and subtraction:

16/36 + 30/36 - 27/36 = (16 + 30 - 27) / 36 = 19/36

Therefore, the result of the expression 4/9 + 5/6 - 3/4 is 19/36.

Answer: 19/36
