Answer 2

To evaluate the given expressions, let's simplify each one step by step:

1. -5/17 : (-25/34): To divide fractions, we multiply the first fraction by the reciprocal of the second fraction: -5/17 ÷ (-25/34) = -5/17 × (-34/25) Now, multiply the numerators and denominators: = (-5 × -34) / (17 × 25) = 170/425 Since both the numerator and denominator have a common factor of 5, we can simplify the fraction: = (170 ÷ 5) / (425 ÷ 5) = 34/85

2. -3/7 : 9/14: Following the same process as above: -3/7 ÷ 9/14 = -3/7 × (14/9) = (-3 × 14) / (7 × 9) = -42/63 Simplify the fraction by dividing both numerator and denominator by their common factor, which is 21: = (-42 ÷ 21) / (63 ÷ 21) = -2/3

3. -39/64 : 13/32: Again, apply the division rule for fractions: -39/64 ÷ 13/32 = -39/64 × (32/13) = (-39 × 32) / (64 × 13) = -1248/832 Simplify the fraction by dividing both numerator and denominator by their common factor, which is 16: = (-1248 ÷ 16) / (832 ÷ 16) = -78/52 Divide both numerator and denominator by their common factor, which is 4: = (-78 ÷ 4) / (52 ÷ 4) = -39/13

Therefore, the results of the given expressions are: -5/17 : (-25/34) = 34/85 -3/7 : 9/14 = -2/3 -39/64 : 13/32 = -39/13
