Answer 2

1. To divide fractions, you need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and the denominator.

Let's solve the first expression step by step:

(-56/81) ÷ (-32/63)

Reciprocal of (-32/63) = (-63/32)

Now, multiply the first fraction by the reciprocal:

(-56/81) * (-63/32)

To simplify, you can cancel out common factors between the numerators and denominators:

(-56/9) * (-7/4)

Multiply the numerators together and the denominators together:

(56 * 7) / (9 * 4) = 392/36

To simplify the fraction further, find the greatest common divisor (GCD) of 392 and 36, which is 4:

392/36 = (392/4) / (36/4) = 98/9

Therefore, the value of (-56/81) ÷ (-32/63) is 98/9.

2. Let's solve the second expression step by step:

(-1 17/18) ÷ (3 1/9)

To simplify the expression, convert the mixed numbers into improper fractions:

(-1 17/18) = (-18/18 + 17/18) = (-35/18)

(3 1/9) = (27/9 + 1/9) = (28/9)

Now, divide the fractions:

(-35/18) ÷ (28/9)

To divide fractions, multiply the first fraction by the reciprocal of the second fraction:

(-35/18) * (9/28)

Again, simplify by canceling out common factors between the numerators and denominators:

(-5/2) * (1/4) = (-5/8)

Therefore, the value of (-1 17/18) ÷ (3 1/9) is (-5/8).
