Answer 2

To solve the equation 4 + 5/18 - 1 + 8/9, we can follow the order of operations (PEMDAS/BODMAS) to simplify the expression step by step.

Step 1: Addition and Subtraction

First, we perform the addition and subtraction operations from left to right.

4 + 5/18 - 1 + 8/9 = (4 + 5/18) - 1 + 8/9

Step 2: Addition and Subtraction of Fractions

Next, we add and subtract the fractions separately.

4 + 5/18 = (4 * 18 + 5) / 18 = 77/18

Now, the equation becomes:

(77/18) - 1 + 8/9

Step 3: Finding a Common Denominator

To add or subtract fractions, we need to find a common denominator. In this case, the common denominator is 18.

(77/18) - 1 + 8/9 = (77/18) - (18/18) + (16/18)

Step 4: Simplifying the Expression

Now, we can combine the fractions:

(77/18) - (18/18) + (16/18) = (77 - 18 + 16) / 18 = 75/18

Step 5: Simplifying the Fraction

Finally, we simplify the fraction:

75/18 = 25/6

Therefore, the solution to the equation 4 + 5/18 - 1 + 8/9 is 25/6.
