Answer 2

To calculate the expression (8 3/17 * 5 1/4) + (3 14/17 * 5 1/4), you can follow these steps:

Step 1: Convert the mixed numbers to improper fractions.

8 3/17 = (8 * 17 + 3) / 17 = 139/17 5 1/4 = (5 * 4 + 1) / 4 = 21/4 3 14/17 = (3 * 17 + 14) / 17 = 65/17

Step 2: Perform the multiplications.

(139/17 * 21/4) + (65/17 * 21/4)

Step 3: Multiply the numerators and denominators separately for each fraction.

[(139 * 21) / (17 * 4)] + [(65 * 21) / (17 * 4)]

Step 4: Perform the multiplications in the numerators and denominators.

[2919/68] + [1365/68]

Step 5: Add the two fractions together.

(2919/68) + (1365/68) = (2919 + 1365) / 68 = 4284/68

Step 6: Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 4.

(4284/4) / (68/4) = 1071/17

So, the result of the expression is 1071/17.
