Answer 2

To solve the expression (-8 3/4) * (-1 3/14), we first need to convert the mixed numbers into improper fractions and then perform the multiplication.

Step 1: Convert the mixed numbers to improper fractions (-8 3/4) = -((8 * 4 + 3) / 4) = -((32 + 3) / 4) = -35/4 (-1 3/14) = -((1 * 14 + 3) / 14) = -((14 + 3) / 14) = -17/14

Step 2: Multiply the improper fractions (-35/4) * (-17/14) = (35/4) * (17/14)

Step 3: Multiply the numerators and denominators Numerator = 35 * 17 = 595 Denominator = 4 * 14 = 56

Step 4: Simplify the fraction (if possible) To simplify, we can find the greatest common divisor (GCD) of the numerator and denominator and then divide both by it.

GCD(595, 56) = 7

Divide both the numerator and denominator by 7: 595 ÷ 7 = 85 56 ÷ 7 = 8

So the simplified result is 85/8.

Therefore, the solution to the expression (-8 3/4) * (-1 3/14) is 85/8.
