Question

(3 1/8 - 2 5/12) * (-1 3/17)

Answer 1

(3 1/8-2 5/12)*(-1 3/17)=-5/6  

1)3 1/8-2 5/12=17/24

2)17/24*(-1 3/17)= 17/24*(-20/17)=-5/6

Answer 2

To solve this expression, follow these steps:

Step 1: Convert the mixed numbers into improper fractions.

• $3 \frac{1}{8} = \frac{3 \cdot 8 + 1}{8} = \frac{25}{8}$
• $2 \frac{5}{12} = \frac{2 \cdot 12 + 5}{12} = \frac{29}{12}$
• $-1 \frac{3}{17} = -\frac{17 + 3}{17} = -\frac{20}{17}$

Step 2: Perform the subtraction within the parentheses. $\frac{25}{8} - \frac{29}{12} = \frac{150}{48} - \frac{116}{48} = \frac{34}{48} = \frac{17}{24}$

Step 3: Multiply the result from step 2 by $-\frac{20}{17}$. $\frac{17}{24} \cdot -\frac{20}{17} = -\frac{17 \cdot 20}{24 \cdot 17} = -\frac{340}{408} = -\frac{85}{102}$

So, $(3 \frac{1}{8} - 2 \frac{5}{12}) \cdot (-1 \frac{3}{17}) = -\frac{85}{102}$.
