Answer 2

To solve the given expression, we'll follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.

The expression is: 3 + 4/27 * 5 + 1/5 + 2 * 3/26 * 5 + 1/5 - 5 - 7/27 - 4 - 1/5

Step 1: Perform multiplication and division from left to right. 3 + 4/27 * 5 = 3 + 20/27 = 3 + 20/27

Step 2: Add the fractions. 3 + 20/27 + 1/5 = 3 + (20/27 * 5/5) + 1/5 = 3 + 100/135 + 27/135 = 3 + 127/135

Step 3: Perform multiplication and division from left to right. 2 * 3/26 * 5 = 2 * 15/26 = 30/26

Step 4: Add the fractions. 3 + 127/135 + 30/26 = 3 + (127/135 * 26/26) + 30/26 = 3 + 3302/3510 + 135/130 = 3 + 3437/3510

Step 5: Perform addition and subtraction from left to right. 3 + 3437/3510 - 5 = 3 - 5 + 3437/3510 = -2 + 3437/3510

Step 6: Simplify the mixed number. -2 + 3437/3510 = -2 + (3437 ÷ 3510) + (3437 mod 3510)/3510 = -2 + 0 + 3437/3510

The final result is: -2 + 3437/3510

If you need a decimal approximation, you can calculate the fraction's decimal value by dividing the numerator (3437) by the denominator (3510) separately.

-2 + 3437/3510 ≈ -2 + 0.9792 ≈ -1.0208
